It explains how to find the angle of an equivalent cofunction. … WebCofunction Identities. In trigonometry, a function f is said to be a cofunction of a function g if. whenever α and β are complementary angles, that is, two angles whose sum is 90° or π/2 radians: Using the sine and cosine subtraction formulas, we have already derived the cofunction identities. Now we will prove other similar formulas.
