Evaluate secant, cosecant, cotangent (radians) » reciprocal identities | Math Hacks

Brett shows you how to evaluate trigonometric functions Secant, Cosecant, and Cotangent at a given radian measure by hand by utilizing special right triangles and the reciprocal identities. You will learn how to set up your diagram, determine the coordinate point at the given angle, as well as use the identities to find your solution including an example of an "undefined" solution in the final problem.
