[2sin^(2)theta-cos^(2)theta=2],[" tind ex value of "]

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

If sin^(4)theta-cos^(4)theta=k^(4) , then the value of sin^(2)theta-cos^(2)theta is

If sin^(2)theta-cos^(2)theta=(1)/(4) , then the value of (sin^(4)theta-cos^(4)theta) is :

If sin^(6) theta + cos^(6) theta -1 = lambda sin^(2) theta cos^(2) theta then the value of lambda is

If sin^(8)theta+cos^(8)theta-1=0 then what is the value of cos^(2)theta sin^(2)theta

sin^(4) theta + cos ^(4) theta + 2sin^(2) theta cos ^(2) theta has value 1.

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

Let f(theta) = sqrt(a^2cos^2theta+b^2sin^2theta) + sqrt(a^2sin^2theta+b^2cos^2theta) Minimum value of [f(theta)]^2

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
