What is the cofunction identity for tan(θ)?

tan(θ) = cot(π/2 - θ)

cot(θ) = tan(π/2 - θ)

sin(θ) = cos(π/2 - θ)

sec(θ) = csc(π/2 - θ)

Answer explanation

The correct cofunction identity for tan(θ) is tan(θ) = cot(π/2 - θ), making the first option the right choice.

Rewrite tan(x) in terms of sin(x) and cos(x).

tan(x) = cos(x)/sin(x)

tan(x) = 1/cot(x)

tan(x) = sin(x)/cos(x)

tan(x) = opp/adj
