Step-by-step explanation:
tan^2theta - sin^2theta
(sin^2theta /cos^2theta) - sin^2theta
= (sin^2theta - sin^2theta cos^2theta ) /cos^theta
= (sin^2theta (1 - cos^2theta) ) / cos^2theta
= (sin^2theta * sin^2theta)/cos^2 theta
= (sin^2theta /cos^2theta) * sin^2theta
= cos^2theta * 1 / cosec^2theta
hence proved
