Question

1/sec theta-tan theta -1/cos theta=1/cos theta-1/sec theta +tan theta

Answer 1

Answer:

$\tan\alpha = \cos \alpha - \sec( \alpha )$

Answer 2

Answer:3no.of solution

Step-by-step explanation:

Costheta-tantheta-sectheta=sec theta - cos theta +tan theta

2costheta - 2tantheta - 2sectheta =0

Theta =0,pi,2pi

After substituting the value...

The equation will be proved
