WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations. WebSine and cosine are each other's cofunctions. In mathematics, a function f is cofunction of a function g if f ( A) = g ( B) whenever A and B are complementary angles. [1] This definition typically applies to trigonometric functions. [2] [3] The prefix "co-" can be found already in Edmund Gunter 's Canon triangulorum (1620). [4] [5]
