tansquare theta-sin square theta is equal to tansquare theta.sinsquare

1.	tansquare theta-sin square theta is equal to tansquare theta.sinsquare theta
Answer» Tan^2=sin^2/cos^2Acc to question..Lhs= sin^2/cos^2-sin^2 = (sin^2-sin^2×cos^2)÷cos^2 Taking sin^2 as common, we get = Sin^2(1-cos^2)÷cos^2 =Sin^2× sin^2/cos^2 Since sin theta÷ cos theta=tan theta, we get Sin^2theta× tan^2 theta Hence proved
