Sin θ/cos θ = tan θ not for 90° & 270° or multiples. Cos θ/sin θ = cot θ not for 0°, 180° & 360° or multiples Reciprocal Identities (Important in Calculus) These come from the definitions and they are just the pairings that relate to being the reciprocal of the given trig f(n) – sin θ, cos θ or tan θ.
