State the three reciprocal relations and the two quotient relations among the trigonometric ratios.
Original Khojo Papers practice question — not from a past board paper.
Answer
The reciprocal relations are cosec θ = 1/sin θ, sec θ = 1/cos θ and cot θ = 1/tan θ. The quotient relations are tan θ = sin θ/cos θ and cot θ = cos θ/sin θ.

Explanation
These, together with sin2θ + cos2θ = 1, generate every other identity at this level.
