(cos teta +sin teta)² |
|
Answer» (sin theta+ COS theta)^2 = sin ^2 theta + cos ^2 theta + 2 sin theta cos theta = 1+ sin 2 theta. one more question for u \begin{GATHERED}If \: tan \theta \: + \frac{1}{tan\theta} = 2\\ find: \\ (1)sin\theta + cos\theta \\ (2)sec\theta + tan\theta\end{gathered} Iftanθ+ tanθ 1 =2 find: (1)sinθ+cosθ (2)secθ+tanθ
