It combines the concepts of algebra and geometry, allowing us to represent geometric shapes and their properties using equations and coordinate systems. \n\nHere's a breakdown of what analytic geometry involves:\n\n* **Coordinate Systems:** Analytic geometry uses coordinate systems, like the Cartesian plane (x-y axes), to represent points and shapes. Each point is assigned a unique pair of coordinates (x, y).\n* **Equations:** Geometric objects, such as lines, circles, and curves, can be represented by algebraic equations. For example, the equation of a straight line is often written as y = mx + c, where m is the slope and c is the y-intercept.\n* **Geometric Properties:** Analytic geometry allows us to study geometric properties like distance, slope, angle, and area using algebraic methods. \n* **Applications:** Analytic geometry has wide applications in various fields, including:\n * **Engineering:** Designing structures, analyzing forces, and modeling motion.\n * **Physics:** Describing trajectories, understanding motion, and analyzing forces.\n * **Computer Graphics:** Creating and manipulating images, animations, and 3D models.\n * **Cartography:** Mapping and representing geographical features.\n\nThe book \"Analytic Geometry (1922)\" you provided is a classic textbook that explores these concepts in detail. It covers topics like:\n\n* **Lines and Equations:** Understanding the relationship between lines and their equations.\n* **Conic Sections:** Studying the properties of parabolas, ellipses, hyperbolas, and circles.\n* **Geometric Magnitudes:** Calculating distances, angles, and areas using coordinate geometry.\n* **Solid Geometry:** Extending analytic geometry to three dimensions.\n\nDo you have any specific questions about analytic geometry or the book \"Analytic Geometry (1922)\"?

In these works Oresme locates points by means of coordinates, somewhat as places are located on a map by means of latitude and longitude. In geographic work this method of location had been used long before by such Greek scholars as Hipparchus, Marinus of Tyre, Ptolemy, and Heron. While there was some revival of interest in conics in the works of such writers as Kepler (1571–1630), it was not until Descartes (Latin, Cartesius, 1596–1650) published his epoch-making little work *La Géométrie*, in 1637, that the fundamental ideas of analytic geometry were laid before the mathematical world. It is true that Fermat (c. 1601–1665), as shown by his correspondence with contemporary scholars, had already conceived the idea that the properties of a curve could be deduced from its equation, but, as in the case of his contributions to the theory of numbers, he published nothing upon the subject, and so the work of Descartes stands as the first to make known the ideas of analytic geometry. Although Descartes had the idea of an analytic geometry for higher dimensions, his work is confined entirely to the plane, and it was left for men like Parent (1700), and especially Clairaut (1731) and Euler (1760), to extend the theory to curves of double curvature and to surfaces.

So complete was this work of Apollonius that it seemed to mathematicians for about eighteen hundred years to have exhausted the subject, and very few additional discoveries were made. Most of the propositions given today in elementary treatises on analytic geometry are to be found in the writings of Apollonius, and some idea of coordinates may also be seen in certain passages of his work. The study of conics by ancient and medieval writers was, however, of a purely geometric type; the proofs of the propositions being of the same general nature as the proofs of the propositions in Euclid's celebrated work on geometry.

Nature of Analytic Geometry The chief features of analytic geometry which distinguish it from elementary geometry are its method and its results. The main results will be found as we proceed, but the method of procedure may be indicated briefly at once. This method consists of indicating by algebraic symbols the position of a point, either fixed or in motion, and then applying to these symbols the processes of algebra. Without as yet knowing how this is done, we can at once see that with the aid of all the algebraic processes with which we are familiar we shall have a very powerful method for exploring new domains in geometry, and for making new applications of mathematics to the study of natural phenomena. The idea of considering not merely fixed points, as in elementary geometry, but also points in motion is borrowed from a study of nature. For example, a ball thrown into the air follows a certain curve, and the path of a plane X about its sun is also a curve, although not a circle. # 5. Point on a Map The method by which we indicate the position of a point in a plane is substantially identical with the familiar method employed in map drawing. To state the position of a place on the surface of the earth, we give in degrees the distance of the place east or west of the prime meridian, that is, the longitude of the place; and then we give in degrees the distance of the place north or south of the equator, that is, the latitude of the place. For example, if the curve NGAS represents the prime meridian, a meridian arbitrarily chosen and passing through Greenwich, and if 14° B’ represent the equator, the position of a place P is determined if AB and BP are known. If AB = 70° and BP = 45°, we may say that P is 70° east and 45° north. ``` Image Analysis: **Text Analysis:** - **Image 1:** - **Detected Text:** - The text is an excerpt from a book discussing analytic geometry and mapping methods.

It is not so elaborate in its details as to be unfitted for practical classroom use; neither has it been prepared for the purpose of exploiting any special theory of presentation; it aims solely to set forth the leading facts of the subject clearly, succinctly, and in the same practical manner that characterizes other textbooks of the series. It is recognized that the colleges of this country generally follow one of two plans with respect to analytic geometry. Either they offer a course extending through one semester or they expect students who take the subject to continue its study through a whole year. For this reason the authors have so arranged the work as to allow either of these plans to be adopted. In particular, it will be noted that in each of the chapters on the conic sections questions relating to tangents to the conic are treated in the latter part of the chapter. This arrangement allows for those subjects being omitted for the shorter course if desired. Sections which may be omitted without breaking the sequence of the work, and the omission of which will allow the student to acquire a good working knowledge of the subject in a single half year are as follows: 46–53, 56–62, 121–134, 145–163, 178–197, 225–245, and part or all of the chapters on solid geometry. On the other hand, students who wish that thorough foundation in analytic geometry should proceed to the study of the higher branches of mathematics are urged to complete the entire book, whether required to do so by the course of study or not.

Two Fundamental Problems The notion of correspondence between graphs and equations gives rise to two problems of fundamental importance in analytic geometry: 1. Given the equation of a graph, to draw the graph. 2. Given a graph, to find its equation. These problems, with the developments and applications to which they lead, form the subject matter of analytic geometry. A few examples illustrating the first of these problems will now be given, the second problem being reserved for consideration in Chapter III. The word *locus* is often employed in place of the word *graph* above. So also is the word *curve*, which includes the straight line as a special case. ## 12. Nature of the Graph of an Equation In general, an equation in x and y is satisfied by infinitely many pairs of real values of x and y. Each of these pairs of values locates a point on the graph of the equation. The set of all points located by these pairs usually forms, as in the examples on page 8, a curve which contains few or no breaks, or, as we say, a curve which is continuous throughout most or all of its extent. In dealing with graphs of equations in the remainder of this chapter, and again in Chapter III, we shall assume that the graphs are continuous except when the contrary is shown to be the case. The study of the conditions under which the graph of an equation is not continuous, together with related topics, is a matter of considerable importance in the branch of mathematics known as the calculus. In special cases it may happen that the graph of an equation consists of only a limited number of real points. For example, the equation \(x^2 + y^2 = 0\) is satisfied only by \(x = 0, y = 0\), and its graph is a single point, the origin.

It mentions the continuity of graphs and the importance of studying conditions under which a graph is not continuous. - Overall, the text outlines fundamental concepts in analytic geometry and the connection between equations and their graphical representations. 3. **Contextual Significance:** - The text likely serves an educational purpose, explaining basic concepts in mathematics related to graphing equations.

By rotating the axes through a properly chosen angle (S 111) we can eliminate the \(B\) term, the equation becoming \[ A'x^2 + E'y + F' = 0, \] an equation which represents an ellipse (S 116), a hyperbola (S 179), or a parabola (S 122, 123). ### THEOREM. EQUATION OF ANY CONIC 201. The equation of any conic referred to rectangular coordinates is of the second degree. **Proof.** The equation of any conic referred to axes taken through any origin \(O\) parallel to certain lines is \[ Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0. \] The equation of the same conic referred to axes through \(O\) making any angle \(\theta\) with the other axes is found by substitutions (S 109) which do not change the degree.

Nature of Analytic Geometry The chief features of analytic geometry which distinguishes it from elementary geometry are its method and its results. The results will be found as we proceed, but the method of procedure may be indicated briefly at once. This method consists of indicating by algebraic symbols the position of a point, either fixed or in motion, and then applying to these symbols the processes of algebra. Without as yet knowing how this is done, we can at once see that with the aid of all the algebraic processes with which we are familiar we shall have a very powerful method for exploring new domains in geometry, and for making new applications of mathematics to the study of natural phenomena. The idea of considering not merely fixed points, as in elementary geometry, but also points in motion is borrowed from a study of railroads.

If \( AB = 70^\circ \) and \( BP = 45^\circ \), we may say that \( P \) is \( 70^\circ \) east and \( 45^\circ \) north, or \( 70^\circ \) E. and \( 45^\circ \) N. ``` Image Analysis: 1. **Localization and Attribution:** - Image 1: The only image on this page. 2. **Object Detection and Classification:** - Detected Objects: - Geometric figures such as circles and lines. - Key Features: - These figures likely represent points, lines, and curves used in geometric or analytic demonstrations. 3. **Scene and Activity Analysis:** - The scene depicts an educational context, with diagrams illustrating concepts in analytic geometry. 4. **Text Analysis:** - Extracted Text: The page contains sections with numeric headings, discussing “Nature of Analytic Geometry” and “Point on a Map.” - Significance: The text explains the application and methodology of analytic geometry, describes the use of algebraic symbols, and discusses mapping techniques. 5. **Diagram and Chart Analysis:** - The geometric diagrams provide visual support for the explanations in the text, such as illustrating point positioning and curves. 9. **Perspective and Composition:** - The perspective is direct and frontal, typical of educational or instructional material.

Simplifying an Equation by Translation. Let us examine the possible effects of translation upon the equation \[ 2x^2 - 3xy + y^2 + 5x - 3y - 10 = 0 \] If the new origin is \((h, k)\), then the new equation is \[ 2(x + h)^2 - 3(x + h)(y + k) + (y + k)^2 + 5(x + h) - 3(y + k) - 10 = 0 \] or \[ 2x^2 - 3xy + y^2 + 5x - 3y + (4h + 5k - 10) = 0 \] Only the \(x\) term, the \(y\) term, and the constant term depend on \(h\) and \(k\). To make the equation simpler, let us determine \(h\) and \(k\) so that the coefficients of two of these terms, say the \(x\) term and \(y\) term, vanish; that is, so that \(4h + 5k - 10 = 0\) and \(-3h + 2k - 3 = 0\). This gives \(k = 1\) and \(h = 3\), and the new equation, referred to axes through \((3, 1)\) and parallel to the old axes, is \[ 2x - 3y + 12 = 0 \] ## 108. Equation \(Ax^2 + By^2 + Cxy + Dy + E = 0\). We shall frequently meet an equation of the second degree which has an \(x^2\) term and a \(y^2\) term but no \(xy\) term. The following example shows an easier method than the one given above for transforming such an equation into an equation which has no terms of the first degree. For example, consider the equation \[ 2x^2 - 6y^2 - 16x - 12y = 0 \] We may first write it in the form \[ 2(x^2 - 6y^2) - 16x - 12y = 0 \] and then \[ 2(x^2 - 6y - 1) + 1 - 32 = -6 = 27. \] It is now obvious that the desired new origin is \((4, -1)\); for, by writing \(x + 2\) for \(x\) and \(y + 1\) for \(y\), we have \[ 2x^2 + 6 = 27. \] Image Analysis: **Text Analysis:** 1. **Image 1:** - **Detected Text:** The image is an excerpt from a mathematics book discussing "Translation of Axes." - **Key Sections:** - Title: "TRANSLATION OF AXES" - Page Number: "111" - Sections: "107.

Algebraic Curve If the equation of a curve referred to the rectilinear coordinates \( x \) and \( y \) involves only algebraic functions of \( x \) and \( y \), the curve is called an **algebraic curve**. We have studied the algebraic curves represented by equations of the first and second degrees. It is a much more difficult matter to discover all the kinds of curves represented by equations of the third degree and by equations of degree higher than the third. Newton was the first to make a searching investigation of the curves represented by equations of the third degree, and according to his classification there are seventy-six kinds. In the first part of this chapter, we shall describe a few curves of special interest: the equations of which are of the third and fourth degrees. ### 226. Transcendent Curve If the equation of a curve referred to rectilinear coordinates involves transcendent functions of \( x \) or \( y \), the curve is called a **transcendent curve**. Such, for example, are the graphs of the equations involving \( \sin 2x \), \( \log 2 \), and \( 10^x \). We shall examine a few of these curves in this chapter. As an example of a useful formula containing a constant raised to a variable power, it is easily seen that the amount of \( \$1 \) at interest compounded annually for \( n \) years is found from the equation \( y = 10^n \), and that the graph of this equation is a transcendent curve.

For either \( c = 0 \) or \( 6 = 0 \): - If \( a > 0 \), the conic is an ellipse. - If \( a < 0 \), the conic is a hyperbola. For them \( c \) and \( d \) must have unlike signs. Since \( ax^2 + bxy + cy^2 + dx + ey + f = 0 \), we see that \( ax^2 + bxy + cy^2 \) is perfect squares if \( b^2 - 4ac = 0 \). Then the conic is a parabola when the terms of the second degree form a perfect square, as in the equation \( ax^2 + bxy + cy^2 = 0 \). ## 203. Central Conics. The ellipse and hyperbola have centers and hence are called central conics. If \( a = b \neq 0 \), an equation of the second degree represents a central conic. ## 204. Standard Equations. We shall refer to the following as the standard equations of the conics: - For the parabola: \[ y^2 = 4px \quad \text{§ 115} \] - For the ellipse: \[ \frac{x^2}{a^2} + \frac{y^2}{b^2} = 1 \quad \text{§ 136} \] - For the hyperbola: \[ \frac{x^2}{a^2} - \frac{y^2}{b^2} = 1 \quad \text{§ 165} \] We now proceed to the problem of reducing the general equation of the second degree to these forms. For the central conics, we move the origin in order to eliminate the \( ax \) terms and \( by \) terms (see § 107), and then we rotate the axes in order to eliminate the \( xy \) term (§ 111). ## 205. Choosing θ. There are always two values of \( \theta \) less than \( 360^\circ \) for which \( 2\theta = \tan^{-1}(\frac{b}{a}) \) and one of them is less than \( 180^\circ \), in which case \( 0^\circ < \theta < 90^\circ \). In the treatment of central conics, we shall always take \( \theta < 90^\circ \).
