Question:

Find A, if tan 2A = cot ( A - 2A0 )

Answer:

tan 2A = cot ( A - 2A0 )

We know tan ( 90° - θ ) = cot θ

➺ cot ( 90° - 2A ) = cot ( A - 2A0)

Now cot on left hand side gets cancel with cot on right hand side.

➺ 90° - 2A = A - 2A0

➺ 90° - 2A = A - 2A × 0

➺ 90° - 2A = A - 0

➺ 90° + 0 = A + 2A

➺ 3A = 90°

➺ A = 90°/3

➺ A = 30°
