" 25.यदि "a sin^(3)theta+b cos^(3)theta=sin theta cos theta" तथा "a*sin theta-b cos theta=0," तो सिद्ध कीजिए "a^(2)+b^(2)=1

3. sin^(3)theta+cos^(3)theta=(sin theta+cos theta)(1-sin theta cos theta)

Prove that: (sin^(3) theta + cos^(3) theta)/(sin theta + cos theta) = 1-sin theta cos theta

If a sin^(3) theta + b cos^(3) theta = sin^(3) theta * cos theta and a sin theta - b cos theta=0 , then prove that a^(2)+b^(2)=1 .

(sin theta+cos theta)(1-sin theta cos theta)=sin^3 theta+cos^3 theta

If 2-cos^(2)theta=3sin theta cos theta where sin theta!=cos theta then tan theta=

If tan theta = 1/b , then ( a sin theta - b cos theta )/( a sin theta + b cos theta) is

sin theta+sin2 theta+sin3 theta=1+cos theta+cos2 theta

If 2 - cos^(2) theta = 3 sin theta cos theta , sin theta ne cos theta then tan theta is

(sin3 theta+cos3 theta)/(cos theta-sin theta)=1+2xx sin2 theta
