Question

How do you prove `tantheta - cot^2theta+cottheta= sin^2theta- cos^2theta`?

Answer 1

Please check the Problem.

Explanation:

The Assertion doesn't seem to be true, as can be seen from

the following :

`"For "theta=pi/4," the L.H.S.="1-1^2+1=1," whereas, "`

`"the R.H.S.="(1/sqrt2)^2-(1/sqrt2)^2=0`.
