# Cot pi 6 exact value of trig

Evaluate trigonometric functions with a calculator. Using Reference Angles to Evaluate Tangent, Secant, Cosecant, and Cotangent We can evaluate trigonometric functions of angles outside the first quadrant using reference angles as we have already done with the sine and cosine functions. Which trigonometric functions are odd? Find the linear speed of a point on the equator of the earth if the earth has a radius of 3, miles and the earth rotates on its axis every 24 hours. The graph is not symmetrical about the y -axis. Describe the secant function. Find the missing sides of the triangle. Show Solution cosine, secant. See Figure.
