If `sin^4 2x+cos^4 2x=sin2x*cos2x` then `x=`

If sin^(2)4x+cos^(2)x=2sin4x cos^(2)x, then

Evaluate int( sin ^4 x+cos ^4 x)/(sin ^2 x cos ^2 x) d x

sin^(4)x+cos^(4)x=1-2sin^(2)x cos^(2)x

Solve :sin x 4 cos x = sin 2x 4 cos 2x.

The value of (cos^(4)x+cos^(2)x sin^(2) x + sin^(2)x)/(cos^(2)x+ sin^(2) x cos^(2) x + sin^(4)x) is ____________

cos^(2)x-2cos x=4sin x-sin2x

2tanx = sin4x - 2sin2x cos2x tan^(2)x

3-2cos x-4sin x-cos2x+sin2x=0

If f(x)=[[1+sin^2x,cos^2x,4sin2x],[sin^2x,1+cos^2x,4sin2x],[sin^2x,cos^2x,1+4sin2x]] what is the maximum value of f(x).
