Evaluating Trig Functions – Explanation and Examples

WebUsing Reference Angles to Evaluate Trigonometric Functions We can find the cosine and sine of any angle in any quadrant if we know the cosine or sine of its reference angle. The absolute values of the cosine and sine of an angle are the same as those of the reference angle. The sign depends on the quadrant of the original angle. WebLike all functions, the sine function has an input and an output. Its input is the measure of the angle; its output is the y-coordinate of the corresponding point on the unit circle. The cosine function of an angle t t equals the x-value of the endpoint on the unit circle of an arc of length t. t. In Figure 3, the cosine is equal to x. x.
