" (viii) "(1+tan^(2)theta)cos theta*sin theta=tan theta

Solve sin^(2)theta tan theta+cos^(2)theta cot theta-sin2 theta=1+tan theta+cot theta

(sin theta+sin2 theta)/(1+cos theta+cos2 theta)=tan theta

(sin theta+sin2 theta)/(1+cos theta+cos2 theta)=tan theta

Prove that (cos theta)/((1-tan theta))-(sin^(2)theta)/((cos theta-sin theta))=(cos theta+sin theta)

Solve sin^2 theta tan theta+cos^2 theta cot theta-sin 2 theta=1+tan theta+cot theta

If tan theta=4 then ((tan theta)/((sin^(3)theta)/(cos theta)+sin theta cos theta)) is equal to

(1-sin theta)/(cos theta)-(cos theta)/(1+sin theta)=2tan theta

Prove that (sin theta+sin 2theta)/(1+cos theta+cos 2 theta)=tan theta

The value of (sin theta+cos theta-1)/(sin theta -cos theta+1)xx(tan^2 theta(cosec^2 theta-1))/(sec theta-tan theta) is:
