Evaluating a trigonometric function
WebMar 27, 2024 · If this property is applied to the trigonometric functions, the following equations that deal with finding an inverse trig function of a trig function, will only be true for values of x within the restricted domains. sin − 1(sin(x)) = x cos − 1(cos(x)) = x tan − 1(tan(x)) = x. These equations are better known as composite functions. WebThree trigonometric functions for a given angle are shown below. sine of theta = -77/85. cosine of theta = 36/85. tangent of theta = -77/36. What are the coordinates of point (x, y) on the terminal ray of angle theta, assuming that the values above were not simplified? (36, -77) The terminal side of an angle in standard position passes through ...
