Find the general solution of tan 2θ tan θ = 1. |
|
Answer» Given, tan 2θ tanθ = 1 ⇒ \(\frac{ 2\,tan\theta}{1-tan^2\theta}\) . tanq =1 ⇒ \(\frac{ 2\,tan\theta}{1-tan^2\theta}\) =1 ⇒2 tan2 θ= 1− tan2 θ ⇒ 3 tan2 θ = 1 ⇒ tan2 θ = \(\frac{1}{3}\) ⇒ tan2 θ = ( \(\frac{1}{\sqrt{3}}\) )2 = tan2 \(\frac{π}{6}\) ⇒ θ = nπ ± \(\frac{π}{6}\) |
