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

If cos 2 theta = - 1/2, "find the value of" cos theta

If sin^(2)theta+3cos theta=2, then find value of cos^(3)theta+sec^(3)theta:

If 2sin^(2)theta=3cos theta, where 0<=theta<=2 pi, then find the value of theta

If 0 le theta lt (pi)/(2) and cos theta+ cos^(2) theta+ cos^(3) theta=1 find the minimum value of tan theta .

If 0

If sin theta_(1)+sin theta_(2)+sin theta_(3), then find the value of cos theta_(1)+cos theta_(2)+cos theta_(3)

If sintheta+sin^(2)theta=1 , then find the value of cos^(2)theta+cos^(4)theta .

If |[1+sin^(2)theta,cos^(2)theta,4sin4theta],[sin^(2)theta, 1+cos^(2)theta,4sin4theta],[sin^(2)theta,cos^(2)theta, 1+4sin4theta]|=0 , then the value of theta is
