Question

for what value of theta, cot 3theta = cot (30+theta)?

Answer 1

Given  : Cot 3θ  = Cot(30° + θ)

cot 3theta cot(30° + theta)​

To Find : θ

Solution:

Cot 3θ  = Cot(30° + θ)

cot has period of π  = 180°

 3θ  = 30° + θ  ± n(180°)

=> 2θ = 30°   + n(180°)

=> θ = 15°    ± n(90°)

θ = 15°    ±  n(90°)

value of theta = 15°    ±  n(90°)
