tan^(2)theta-sin^(2)theta-tan^(2)theta sin^(2)theta

tan^2theta-sin^2theta=tan^2theta.sin^2theta

Prove that tan^2 (theta)-sin^2 (theta)= tan^2 (theta) sin^2 (theta)

Prove that (2sin theta-sin2 theta)/(2sin theta+sin2 theta)=tan^(2)backslash(theta)/(2)

Prove that (2 sin theta - sin 2theta)/(2 sin theta + sin 2theta) = tan^2\ theta/2

If theta=30o, verify that: (i) tan2 theta=(2tan theta)/(1-tan^(2)theta)( ii) sin2 theta=(2tan theta)/(1+tan^(2)theta)

Prove that : tan^2 theta -sin^2 theta =tan^2 theta sin^2 theta .

If tan theta=(a)/(b) then b cos2 theta+a sin2 theta=

If tan theta=b, then cos2 theta+b sin2 theta=
