If p cotθ = √q2−p2, then the value of sinθ is ___. (θ being an acute angle).
pq
q2p
q3p

Given, p cotθ = √q2−p2
∴ cotθ = √q2−p2p
Using the identity, cosec2θ = 1 + cot2θ = 1 + q2−p2p2 = q2p2
Hence, cosecθ = qp ∴ sinθ = pq .
If p cotθ = √q2−p2 where θ is an acute angle , then the value of sinθ is___.
If sinθ=12 and θ is an acute angle, then find the value of (3cosθ−4cos3θ)?
