Question

Which is the correct cofunction identity for tan0

A. csco(90° - 0)
B. sec(90° - 0)
C. sin(90° - 0)
D. cos(90° - 0) E. cot(90°-0

Answer 1

TRUE

Explanation:

Answer 2

E. cot(90° -θ)

Explanation:

The "cofunction" is named by adding or deleting the "co" in front of the function name. The cofunction for tangent is cotangent.

The tangent of an angle is the cotangent of the complement of the angle:

tan(θ) = cot(90° -θ)
