Question

sin^2 theta + cos^2 theta + cot^2 theta

Answer 1

Answer:

sin²Ф+cos²Ф+cot²Ф= 1 + cot²Ф

                                =cosec²Ф

Answer 2

$\sin^2 \theta + \cos^2 \theta + \cot^2 \theta \\ \\ \Rightarrow\ 1+\cot^2\theta \\ \\ \Rightarrow\ \bold{csc^2 \ \theta}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\csc^2\theta-\cot^2\theta=1\ \ ; \ \ \csc^2\theta=1+\cot^2\theta]$
