What is a reciprocal trig function?

Answer 1

sin theta and csc theta are reciprocal functions because sin = y/r and csc = r/y

you use the same 2 sides of a triangle, but you use the reciprocal.

Answer 2

A reciprocal trigonometric function is the ratio of the reciprocal of a trigonometric function to either the sine, cosine, or tangent function. The reciprocal of the sine function is the cosecant function, the reciprocal of the cosine function is the secant function, and the reciprocal of the tangent function is the cotangent function. These functions are useful in solving trigonometric equations and graphing trigonometric functions.
