Step-by-step explanation:
(cosec^2 theta -1) tan^2 theta
= take cosec^2 theta as 1÷sin^2 theta and take tan^2 theta as sin^2 theta ÷cos^2theta
=( 1÷sin^2theta-1)(sin^2theta ÷cos^2theta)
= (1-sin^2theta÷sin^2theta)(sin^2theta÷cos^2theta)
( 1-sin^2theta= cos^2theta)
= (cos^2theta÷sin^2theta)(sin^2theta÷cos^2theta)
it will get cancelled and becomes one
Then the answer is one
I hope this will help you
