Question

if 3 theta is an acute angle solve the following equation for theta

(cosec 3theta - 2) (cot 2theta - 1) = 0​

Answer 1

Answer:

cosec3α−2)(cot2α−1)=0

Either,

cosec 3∝-2 = 0 or cot2∝-1 = 0

cosec 3∝ = 2 cot 2∝ = 1

cosec 3∝ = cosec π/6 cot 2∝ = cot π/4

∝ = π/18 ∝ = π/8

Hence ∝ = 10° or 22.5°
