`sin^(4) theta + cos^(4) theta` in terms of ` sin theta` is ______

What is the simplified form of cos^(4)theta- sin^(4) theta in terms of sin theta

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

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

If sin theta + sin^(2) theta =1 then cos^(4) theta + cos^(8) theta + 2 cos^(6) theta =

(sin theta + cos theta)/(sin theta - cos theta) + (sin theta - cos theta)/(sin theta + cos theta)= ________

If 3 sin theta + 4 cos theta=5 , then find the value of 4 sin theta-3 cos theta .
