" Prove that "(2sqrt(2)pi/9+(sin theta-2sin^(3)theta)/(2cos^(3)theta-cos theta)=tan theta

Prove that (sin theta - 2 sin^(3) theta)/(2 cos^(3) theta - cos theta) = tan theta

( sin theta - 2 sin ^ 3 theta ) / (2 cos ^ 3 theta - cos theta ) = tan theta

Prove that: (sin theta - 2 sin^(3) theta) = (2cos^(3) theta - cos theta) tan theta .

Prove that ("sin"theta-2"sin"^(3)theta)/(2"cos"^(3)theta-"cos"theta)="tan"theta

Prove that (Sin theta)/(1-cos theta)=cosec theta+cot theta OR Prove that (Sin theta - 2 Sin^(3) theta)/(2cos^(3)theta-cos theta)=tan theta
