Solve sin^(2) theta gt cos^(2) theta .

Solve sin^(2) theta gt cos^(2) theta .

Find the least value of 2 sin^(2) theta+ 3 cos^(2) theta .

If "cosec" theta = sqrt5 , find the value of : 2+1/(sin^2theta)-(cos^2theta)/(sin^2theta)

Prove the following identity: (2sinthetacostheta-costheta)/(1-sintheta+sin^2theta-cos^2theta)=cottheta

Solve : 7 sin^(2) theta + 3 cos^(2) theta = 4 .

a sin^(2) theta + b cos^(2) theta =c implies tan^(2) theta =
