If -1

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

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

If (2 sin theta )/(1+ cos theta + sin theta )=x, find the value of (1- cos theta + sin theta )/(1+ sin 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 sin theta_1 + sintheta_2 + sin theta_3=3, then find the value of cos theta_1 + cos theta_2 + cos theta_3.

If 0^(@) < theta < 90^(@) "and" cos theta + sin theta = sqrt2,"find the value of" cos 3 theta.

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

If sqrt3 tan theta = 3 sin theta , find the value of sin theta^2 theta - cos^2 theta , where theta ne 0 .
