यदि `sin theta- cos theta =0` तब सिद्ध कीजिए कि `sin ^(4)theta+cos ^(4) theta =1/2`

If sin theta + cos theta = a " then " sin^(4) theta + cos^(4) theta =

If (sin theta + cos theta)/(sin theta - cos theta)=3 , then the value of sin^(4)theta - cos^(4)theta is:

(sin ^ (4) theta + cos ^ (4) theta) / (1-2sin ^ (2) theta cos ^ (2) theta) = 1

Prove that sin^(4) theta + cos^(4) theta = 1 - 2 sin^2 theta cos^(2) theta

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

If sin theta- cos theta=0 then show that sin^4 theta+cos^4 theta=1/2

If sin theta+cos theta=a then sin ^(4) theta+cos ^(4) theta=

If 5 sin theta-4cos theta=0, 0^@ यदि 5 sin theta-4cos theta=0, 0^@< theta< 90^@ ,है, तो (5 sin theta-2cos theta)/(5 sin theta+3cos theta) का मान होगा :

If 5 cos theta -12 sin theta =0 , the value of (2 sin theta +cos theta )/(cos theta - sin theta ) यदि 5 cos theta -12 sin theta =0 , है, तो (2 sin theta +cos theta )/(cos theta - sin theta ) का मान ज्ञात करें |
