Question

prove that identity in trigonometry​

Answer 1

Answer:

It's a proof. So detailed explanation below.

sec square a + cosec square a

= 1+ tan square a + 1 + cot square a

( using sec square a = 1 + tan square a and cosec square a= 1+ cot square a )

= 1+ tan square a + 1 + cot square a

= tan square a + cot square a +2
