Question

How do you verify the identify `sinthetasecthetacottheta=1`?

Answer 1

see below

Explanation:

`sin theta sec theta cot theta =1`

Left Side : `=sin theta sec theta cot theta`

`=sin theta ( 1/cos theta) (cos theta / sin theta)`

`=cancel sin theta 1/cancel cos theta cancel cos theta/cancel sin theta`

`=1`

`=` Right Side
