"WebDec 20, 2024 · We can interpret the tangent of a negative angle as tan( − θ) = sin( − θ) cos( − θ) = − sinθ cosθ = − tanθ. Tangent is therefore an odd function. The cotangent identity, cot( − θ) = − cotθ, also follows from the sine and cosine identities. We can interpret the cotangent of a negative angle as cot( − θ) = cos( − θ) sin( − θ) = cosθ − sinθ = − cotθ. " - Can tan theta be negative
