P3 Chapter 3 Trigonometric Functions | PDF | Trigonometric Functions | Trigonometry The document covers key concepts and examples related to trigonometric functions, including evaluating functions given points, quadrantal angles, reference angles, and using the unit circle. Find the exact value of each of the six trigonometric functions of a positive angle θ if ( 4 , − 3 ) is a point on its terminal side. if sin θ < 0 and cos θ < 0 , name the quadrant in which the angle θ lies. let θ denote an angle that lies in a quadrant.

Evaluate trigonometric functions of any angle. find reference angles. evaluate trigonometric functions of real numbers. Recall that the trigonometric functions were previously defined for right angle triangles as follows. although these definitions work for angles from 0° to 90° they do not work for obtuse angles. trigonometric ratios can be defined for angles in standard position on a coordinate axis, as shown below. 2 . In this chapter we investigate the trigonometric functions. when you first encountered the trigonometric functions it was probably in the context of “triangle trigonometry,” defining, for example, the sine of an angle as the “side opposite over the hypotenuse.”.

This chapter summa rizes the main definitions and properties of trigonometric functions. even if you are thoroughly familiar with this topic it is still a good idea to scan this material to glean the notation and conventions used in this text. trigonometric functions are actually very simple. Choose the one alternative that best completes the statement or answers the question. point on the terminal side of angle θ is given. find the exact value of the indicated trigonometric function. find sin θ. find cos θ. find sin θ. find sec θ. find tan θ. name the quadrant in which the angle θ lies. find the reference angle of the given angle. Angles trigonometry means “measurement of triangles.” an angle is determined by rotating a ray about its endpoint, called a vertex . the starting position of the ray is the initial side of the angle, and the position after the rotation is the terminal side .
