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

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

(sin5 theta-2sin3 theta + sin theta) / (cos5 theta-cos theta) = tan theta

(cos^(2)theta)/(sin theta)-cosec theta+sin theta=0

If 3cos theta-4sin theta=2cos theta+sin theta then find 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

(sec^(2)theta-sin^(2)theta)/(tan^(2)theta)=cosec^(2)theta-cos^(2)theta

Prove that (sin theta+ sin 2theta + sin 3 theta)/(costheta+cos2theta+cos3theta)=tan 2 theta
