Question

(1-cos square theta)cosec square theta is equal to 1

Answer 1

LHS=(1-cos square theta)cosec square theta

=(sin square theta)cosec square theta........(1-cos square theta =sin square theta)

=sin square theta ×(1/sin square theta)......(cosec theta = (1/ sin theta )

=1

LHS=RHS

hence it is proved that

(1-cos square theta)cosec square theta =1

Hope it helps you .
