sin2 theta tan theta+1=sin2 theta+tan theta

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

Solve : (0^@le thetale90^@) : 2 sin theta tan theta +1=tan theta+2 sin theta

(iii) tan theta-sin theta=sin theta tan theta-1

(2sin theta tan theta(1-tan theta)+2sin theta sec^(2)theta)/((1+tan theta)^(2))=(2sin theta)/(1+tan theta)

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

(2sin theta*tan theta(1-tan theta)+2sin theta*sec^(2)theta)/((1+tan theta)^(2))=(2sin theta)/(1+tan theta)

Find the value of tan ^2theta sin^2 theta+ sin^2 theta-tan^2theta-1 =0

(tan theta+sin theta)/(tan theta-sin theta)=(sec theta+1)/(sec theta-1)
