(cos teta +sin teta)²​

Answer»

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
