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

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

If 5sin^(2)theta+3cos^(2)theta=4 . Find the value of sin theta and cos theta :

If cos^(2)theta+2sin^(2)theta+3cos^(2)theta+4sin^(2)theta+......20terms=10025 and theta is an acute angle then the value of sin theta-cos theta is

If 7sin ^2theta +3cos^2theta =4 , prove that, tan theta =pm1/sqrt(3) .

If 7sin^2theta + 3cos^2theta=4 ,then the value of sectheta+cosectheta is

If tan theta=(3)/(4), then (4sin^(2)theta-2cos^(2)theta)/(4sin^(2)theta+3cos^(2)theta)

If tan theta=(3)/(4), then (4sin^(2)theta-2cos^(2)theta)/(4sin^(2)theta+3cos^(2)theta)

If sin theta+cos theta=(5)/(4) then find the value of sin^(6)theta+cos^(6)theta+7sin^(2)theta*cos^(2)theta

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