(1)/(2ln(sin theta-2sin3 theta)/(2cos3 theta-cus theta)=tan theta)

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

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

((sin theta-2 sin^3 theta)/(2 cos^3 theta- cos theta))^2-1, theta ne 45^@ , is equal to: ((sin theta-2 sin^3 theta)/(2 cos^3 theta- cos theta))^2-1, theta ne 45^@ का मान किसके बराबर है ?

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

(1+sin2 theta-cos2 theta)/(1+sin2 theta+cos2 theta)=tan theta

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