RHS..
tan^2theta -sin^2 theta
Sin^2theta/cos^2 theta.-sin^2theta
Sin2theta(1/cos2theta -1)
Sin2theta (1-cos2theta/cos2theta)
Sin2theta(sin2theta/cos2theta)
Sin2theta.tan2theta
LHS
tan^2theta -sin^2 theta
Sin^2theta/cos^2 theta.-sin^2theta
Sin2theta(1/cos2theta -1)
Sin2theta (1-cos2theta/cos2theta)
Sin2theta(sin2theta/cos2theta)
Sin2theta.tan2theta
LHS
