Cofunction identities calculator

We have six identities that can be obtained using right triangles, the angle sum property of a triangle, and trigonometric ratio formulas. The cofunction identities establish a relationship between trigonometric functions \ (sin\) and \ (cos\), \ (tan\) and \ (cot\), and \ (sec\) and \ (csc\). These functions are known as cofunctions of each other.
