Question

Prove that tan square theta +cot square theta +2=cosec square theta *sec square theta

Answer 1

R.H.S
=cosec square theta × Sec square theta
=(1+cot square theta)(1+tan square theta)
=1+tan square theta + cot square theta+cot squaretheta×tan square theta
=1+tan square theta+ cot square theta+ 1/tan square theta×tan square theta
=1+tan square theta +cot square theta +1
=2+ tan square theta + cot square theta
