Evaluate for `theta` :
`Sin^4theta + Cos^4theta = 5/8`

sin^(4)theta+cos^(4)theta=(5)/(8)

Find te valueof 1-2sin^2theta + sin^4theta . (A) sin^4theta (B) cos^4theta (C) tan^4theta (D) sec^4theta

Show : Sin^4theta - Cos^4theta = Sin^2theta - Cos^2theta

1-8 cos ^(2) theta + 8 cos ^(4) theta= A) sin 4 theta B) cos 4 theta C) sin ^(4) theta + cos ^(4) theta D) sin ^(4) theta - cos ^(4) theta

The number of values of theta satisfying 4 cos theta+3 sin theta=5 as well as 3 cos theta + 4 sin theta = 5 is

4 sin theta * cos^(3) theta-4 cos theta * sin ^(3)theta= A) 4 cos theta B) cos 4 theta C) 4 sin theta D) sin 4 theta

If 4 tan theta = 3 , evaluate (4 sin theta - cos theta +1)/(4 sin theta + cos theta -1)

If sec theta =(5)/(4),"find the value of "((2cos theta - sin theta ))/((cot theta - tan theta ))=.

If sin theta cos theta = sqrt3//4 ,then the value of sin^4theta + cos^4 theta is

Smallest positive value of theta satisfying 8sin theta cos2 theta sin3 theta cos4 theta=cos6 theta is
