Solve `sin^2theta-costheta=1/4`

Solve sin^(2) theta-cos theta=1/4, 0 le theta le 2pi .

Solve: sin^(2)theta+2costheta+1/4=0

If the equation sin^(2)theta-costheta=(1)/(4), then the value of theta lying in the interval 0lethetale2pi is

Solve 6sin^2theta-11sin theta+4=0

Solve the following equation: sin^(2)theta-cos theta=(1)/(4)

Solve: cos3theta+2costheta=0

Solve sin^(3)theta cos theta-cos^(3)theta sin theta=(1)/(4)

Solve cos^(2)theta+sin theta=1

Solve: sin2theta+sin4theta=costheta+cos3theta
