Answer 1

Answer:

1

Step-by-step explanation:

L.H.S= tan^2 theta + cot^2 theta

1+tan^2 theta. 1+ cot^2 theta

= tan^2 theta + cot ^2 theta.

sec^2 theta. cosec^2 theta

= tan^2 theta +. cot^2 theta.

1. 1

cos^2 theta sin^2 theta

= tan^2 theta*cos^2 theta+cot^2 theta*sin^2 theta

= sin^2 theta *cos^2 theta + cos^2 theta *sin^2 theta

cos^2 theta sin^2 theta

= sin^2 theta+ cos^2 theta

= 1

= R.H.S
