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)\"?

Area of a Triangle Given the coordinates of the vertices of a triangle, the area of the triangle may be found by a method similar to the one used in surveying. In this figure, draw the line \( RQ \) through point \( P \) parallel to \( OX \), and draw perpendiculars from \( F_2 \) and \( F_1 \) to \( RQ \). Then, \[ A_{TR} = \text{Area of Trapezoid } HQRF = A_{RFE} - A_{RFQ} \] Noting that the altitude of the trapezoid is \( h_2 \), we can easily find the areas of the figures and can show that \[ A_{RPR} = \frac{1}{2} \left( x_{2} - x_{1} \right) \left( y_{1} + y_{2} - y_{3} \right) \] The student who is familiar with determinants will find that this equation may be written in a form much more easily remembered, as here shown. The area of a polygon may be found by adding the areas of the triangles into which it can be divided. # 31. Positive and Negative Areas Just as we have positive and negative lines and angles, so we have positive and negative areas. When we trace the boundary of a plane figure counterclockwise, we consider the area as positive, and when we trace the boundary clockwise, we consider the area as negative. For example, calling the area of this triangle \( T \), if we read the vertices in the order \( (1, 3), (2, 7), (1, 4) \), we may say that \( T \) is positive; but if we read them in the reverse order, we say that \( T \) is negative. Usually, however, we are not concerned with the sign of an area, but merely with its numerical value. ``` Image Analysis: ## Analysis of the Visual Content ### Image Analysis 1. **Localization and Attribution:** - This is a single image representing a page from a document. - Assign this as **Image 1**. 2. **Object Detection and Classification:** - **Image 1**: Contains mathematical text, geometric figures, and equations. - Objects include textual content and a geometric diagram illustrating a triangle and trapezoid with notations. 3. **Scene and Activity Analysis:** - **Image 1**: The scene is an instructional text page focused on geometry and mathematics.

Properties of the Parabola Draw the figure given on page 126, and prove that: 1. The tangent at \( P_1 \) bisects \( \angle P_1 \) at right angles. 2. The lines \( TP', TP \), and the \( y \)-axis meet in point \( A \). 3. The line joining \( A \) and \( L \) is perpendicular to \( TP' \). 4.

EQUIVALENT EQUATIONS 89. The equations \( Ax + By + C = 0 \) and \( A'x + B'y + C' = 0 \) represent the same line if and only if the corresponding coefficients are proportional. **Proof.** The equations represent the same line if and only if either can be reduced to the other by multiplying its members by a constant, say \( k \). Then the equations \( Ax + By + C = 0 \) and \( kA'x + kB'y + kC' = 0 \) are the same term for term, so that \( \frac{A}{A'} = \frac{B}{B'} = \frac{C}{C'} \). That is, \[ \frac{A}{A'} = \frac{B}{B'} = \frac{C}{C'} \] For example, if \( x + y = 0 \) and \( 4x + 3y = 12 \) represent the same line, then \( \frac{1}{4} = \frac{-1}{3} \) and hence \( m_1 = -1 \), \( m_2 = -4 \). The above proof assumes that \( A' \neq 0 \), \( B' \neq 0 \). If \( A = 0 \), \( B = 0 \), and both \( A' \) and \( B' \) disappear from the equations. Similar remarks apply if \( B = 0 \) or \( C = 0 \). ## Exercise 26.

Find the equation if the line \( y = 2x + 3 \) passes through the intersection of the lines \( 4x + 3y = 17 \) and \( 2y = 10 \). 5. Show that the lines \( 2x + y - 5 = 0 \), \( z - 2y = 0 \), and \( x + y - 6 = 0 \) are concurrent. **Hint:** Show that the third line, \( 2 + 3y - 4 = 0 \), is the same as the line \( mx + by + c + k = 0 \) for a certain value of \( k \).

An abridged edition has been prepared, however, for students who study the subject for only one semester and who do not care to purchase the larger text. It will be observed that the work includes two chapters on solid analytic geometry. These will be found quite sufficient for the ordinary reading of higher mathematics, although they do not pretend to cover the ground necessary for a thorough understanding of the geometry of three dimensions. It will also be noticed that the chapter on higher plane curves includes the more important curves of this nature, considered from the point of view of interest and applications. A complete list is not only unnecessary but undesirable, and the selection given in Chapter XII will be found ample for our purposes.

Then the equations \(Ax + By + C = 0\) and \(k(A'x + B'y + C') = 0\) are the same term for term, so that \(kA' = A\), \(kB' = B\), and \(kC' = C\).

Angle from One Line to Another When we speak of the angle between \( AB \) and \( CD \), we use an ambiguous expression, inasmuch as there are two supplementary angles formed by these lines, namely, \( \alpha \) and \( \beta \). To avoid this ambiguity, we shall speak of the angle from \( AB \) to \( CD \) as the smallest positive angle starting from \( AB \) and ending at \( CD \). In the figure, the angle from \( AB \) to \( CD \) is \( \beta \), either \( BCD \) or \( ARC \), but not \( DAB \). The angle from \( CD \) to \( AB \) is either \( DAB \) or \( BID \). ## 23. Parallel Lines Since a transversal cutting two parallel lines makes corresponding angles equal, it is evident that parallel lines have the same slope. In this figure, \( \alpha_1 = \alpha_2 \) and hence \( m_1 = m_2 \), since they are the tangents of equal angles. The angle from one line to the other is \( 0^\circ \) in the case of parallel lines. ## 24. Perpendicular Lines If we have two lines, \( l_1 \) and \( l_2 \), perpendicular to each other, we see by the figure that \[ \gamma = 90^\circ + \alpha_1 \] and hence we have \[ \tan \gamma = -\cot \alpha_1. \] Thus, \[ \frac{1}{m_1} = -m_2. \] Hence, \( m_1 = -\frac{1}{m_2} \) where \( m_1 \) is the slope of \( l_1 \) and \( m_2 \) is the slope of \( l_2 \). That is, the slope of either of two perpendicular lines is the negative reciprocal of the slope of the other. The condition \( m_2 = -\frac{1}{m_1} \) is sometimes written as \( m_1 m_2 = -1 \) or \( m_1 + 1 = 0 \). This law has many applications in analytic geometry.

By elementary geometry, \( P \) divides \( AB \) in extreme and mean ratio if: \[ AP : PB = PB : PA \] The absence of \( P \) can be noted, and thus: \( AP = P_1 \), \( PB = P_2 \), \( P_1 : P_2 = m : n \) and \( \frac{AP}{PB} = \frac{P_1}{P_2} \).

Given that \( AP = PB \), \( AP \) is perpendicular to \( PB \), \( A \) is \( (2, 3) \), and \( B \) is \( (-3, -2) \), find the coordinates of \( P \). 62. The mid point of the hypotenuse of a right triangle is equidistant from the three vertices. This theorem, familiar from elementary geometry, makes no mention of axes. We, therefore, choose the most convenient axes, which, in this case, are the vertices \( A(0,0) \) and \( B(0,b) \), from the foot of \( M \) and the distances referred to in the exercise. 63. In any triangle \( ABC \), the line joining the mid points of \( AB \) and \( AC \) is parallel to \( BC \) and is equal to \( \frac{1}{2} BC \). The triangle may be regarded as given by the coordinates of the points. 64. Using oblique axes, prove from this figure that the diagonals of a parallelogram bisect each other. ![Figure](../path/to/figure1) In proving this, it is familiar from analytic geometry that it is convenient to use oblique axes as shown by the figure. Thus the diagonals have the same mid-point. 65. The lines joining in succession the mid points of the sides of any quadrilateral form a parallelogram. 66. Using rectangular axes as shown in the figure, prove that the diagonals of a rectangle bisect each other. ![Figure](../path/to/figure2) 67. The diagonals of a rhombus are perpendicular to each other. Since we have not studied the slope of a line with respect to oblique axes, we have neither rectangular nor oblique axes. We may use the figure of \( K(0,0) \), making \( O(2,0) \) and the coordinates \( G(f,g) \) and \( H \) with the coordinates of \( P \) at \( N \). 68. The vertices of a triangle are \( A(0, 0) \), \( B(4, 5) \), and \( C(6, -1) \). If \( H \) divides \( AB \) in the ratio \( 3:1 \), and \( P \) is a point on \( AC \) such that the area of the triangle \( APM \) is half the area of \( ABC \), in what ratio does \( P \) divide \( AC \)? ``` Image Analysis: ### 1.

Parallel Lines Since two lines are parallel if they have the same slope, the equations \( Ax + By + C = 0 \) and \( Ax' + By' + C' = 0 \) represent parallel lines if \( m = m' \). For example, the lines \( 2x - y = 7 \) and \( 4x - 2y = 6 \) are parallel, since \( \frac{A}{B} = \frac{A'}{B'} \) or \( \frac{2}{-1} = \frac{4}{-2} = 2 \). ## 73. Perpendicular Lines Since two lines with slopes \( m \) and \( m' \) are perpendicular to each other when \( m \cdot m' = -1 \) (See §24), two such lines are represented by the equations \( y = mx + b \) and \( y = -\frac{1}{m}x + v \). The equations \( Ax + By + C = 0 \) and \( Ax' + By' + C' = 0 \) represent two lines perpendicular to each other if: \[ -\frac{A}{B} \cdot -\frac{A'}{B'} = -1 \quad \text{or} \quad AB' + A'B = 0 \] This condition is often written \( AA' + BB' = 0 \). If \( Ax + By + C = 0 \) is the equation of a certain line, then the line \( Ax' + By' + C' = 0 \) is parallel to the given line and the line \( Ay + H = 0 \) is perpendicular to the given line. ## 74. Lines at any Angle The angle \( \theta \) from one line, \( y = mx + b \), to another, \( y = m' x + c' \), may be found from the relation: \[ \tan \theta = \frac{m' - m}{1 + mm'} \] In the case of the pair of lines \( Ax + By + C = 0 \) and \( Ax' + By' + C' = 0 \), we have \( m = -\frac{A}{B} \) and \( m' = -\frac{A'}{B'} \); hence: \[ \tan \theta = \frac{-\frac{A'}{B'} + \frac{A}{B}}{1 + \left(-\frac{A}{B}\right)\left(-\frac{A'}{B'}\right)} = \frac{AB' - A'B}{AA' + BB'} \] Image Analysis: **Image 1 Analysis** 1. **Localization and Attribution:** - This is the only image on the page. 2. **Text Analysis:** - The text discusses mathematical concepts related to lines and their properties. - **Topic:** Parallels and Perpendiculars - **Sections Identified:** - **72.

Find the point \( P \) such that the triangles \( BAP \), \( ACP \), and \( CBP \) are equivalent. Because of the double sign (\( \pm \)) in the formula for the distance from a line to a point, there are four cases. 49. On the lines \( AB \), \( BC \), and \( CA \) lay off the segments \( 4 \), \( 5 \), and \( 2 \) respectively, and find \( P \) such that the triangles having \( P \) as a vertex and these segments as bases are equivalent. 50. Consider Ex. 49 for the case in which the three segments are \( a \), \( b \), and \( c \) respectively. 51. Let the three lines \( L_a \), \( L_b \), and \( L_c \) be \( y = mx + b \), \( y = m_1x + b_1 \), and \( y = m_2x + b_2 \) respectively. Then on \( L_a \), locate the points \( (x_a, y_a) \) and \( (x_a', y_a') \); on \( L_b \), the points \( (x_b, y_b) \) and \( (x_b', y_b') \); and on \( L_c \), the points \( (x_c, y_c) \) and \( (x_c', y_c') \). 52. The three pairs of corresponding sides of the triangles \( ABC \) and \( A'B'C' \) in Ex. 51 meet in collinear points. The corresponding sides are \( AB \) and \( A'B' \), \( BC \) and \( B'C' \), and \( CA \) and \( C'A' \), not in all similar cases hereafter. Taking any triangle \( ABC \), letting the \( x \)-axis lie along \( AB \) and the \( y \)-axis based at \( A \), and denoting the vertices by \( A(0, 0) \), \( B(a, 0) \), \( C(c, b) \), proceed as follows: 1. Find the common point \( P \) of the perpendicular bisectors of the sides. 2. Find the common point \( M \) of the medians. 3. Find the common point \( I \) of the altitudes. 4. Show that the points \( P, M, \) and \( H \) referred to in Exs. 53-56 are such that \( PM : MH = 1 : 2 \). It is not necessary to find the lengths \( PM \) and \( MH \).

Hence the plane \( H \) contains \( l \). Furthermore, every plane which contains \( l \) is represented by the last equation. For if the point \( (x_k, y_k, z_k) \) is any point in space, the substitution of \( x_k, y_k, z_k \) for \( x, y, z \) respectively leaves \( k \) as the only unknown quantity in the equation, and therefore \( k \) can be determined in such a way that the plane \( H \) passes through the point \( P_t \). In the special case when \( P_1 \) is on the first plane, we set \( k = 0 \). But when \( P_2 \) is on the second plane, there is no finite value of \( k \) and in this case it is sometimes said that \( k \) tends to infinity. ## 272. STRAIGHT LINES. Any straight line in space may be regarded as the intersection of the two planes \[ Ax + By + Cz + D = 0 \] and \[ A'x + B'y + C'z + D' = 0. \] Therefore the coordinates of every point \( (x, y, z) \) on the line satisfy both of these equations; and, conversely, every point \( (x, y, z) \) whose coordinates satisfy both equations is a point on the line. We therefore say that a straight line in space is represented by two equations of the first degree, regarded as simultaneous. ``` Image Analysis: Here is a detailed analysis of the visual content: 1. **Localization and Attribution:** - The image is a single page from a mathematical text, possibly scanned or photographed. 2. **Text Analysis:** - The page is from a mathematical publication focusing on geometry, specifically "Point, Plane, and Line." - It includes a theorem (271) about "Planes Through a Line" and a proof explaining the theorem. - Another theorem (272) titled "Straight Lines" is described, focusing on the intersection of planes. - The text discusses equations of planes and lines, emphasizing their mathematical properties and relationships. 4. **Text Content Significance:** - The text provides mathematical definitions and proofs concerning geometric concepts, likely intended for advanced study or reference in mathematics or physics. - It highlights important mathematical principles regarding how planes and lines interact in space. 5. **Diagram and Chart Analysis:** - There are no diagrams or charts in this image, so no analysis can be conducted. 6. **Perspective and Composition:** - The perspective is that of a typical book page, with standard text alignment and formatting suitable for academic publications. 7. **Color Analysis:** - The page is primarily black and white, consistent with standard printed materials, aiding in clarity and readability. 8. **Contextual Significance:** - This page appears to be from a specialized mathematical text, contributing to the overall comprehension of geometric principles. - It's likely part of a comprehensive section on geometry in an educational or reference context.
