Introduction to Algebra and Trigonometry provides a complete and self-contained presentation of the fundamentals of algebra and trigonometry. This book describes an axiomatic development of the foundations of algebra, defining complex numbers that are used to find the roots of any quadratic equation. Advanced concepts involving complex numbers are also elaborated, including the roots of polynomials, functions and function notation, and computations with logarithms. This text also discusses trigonometry from a functional standpoint. The angles, triangles, and applications involving triangles are likewise treated. Other topics include analytic geometry, conic sections, and use of a coordinate system to prove theorems from plane, and matrix operations and inverses. This publication is valuable to students aiming to gain more knowledge of the fundamentals of mathematics.Answer 67 meters There are two technical terms which will occur frequently in our word problems. The angle of elevation is the angle between the horizontal and the line of sight. In Figure 18a, 6 is the angle of elevation of the top T of a tree from a point x meters from the base of the tree. T. W. M (a) (b) FIGURE 18 The angle of depression is the angle between the horizontal and the line of sight whenanbsp;...
