If `x sin^3 theta+ y cos^3 theta = sin theta cos theta and x sin theta = y cos theta,` Find the value of `x^2 + y^2.`

If x sin^(3) theta + y cos^(3) theta = sin theta cos theta and x sin theta = y cos theta , then the value of x^(2) + y^(2) is :

If x sin^(3) theta + y cos^(3) theta = sin theta cos theta ne 0 and x sin theta - y cos theta = 0 , then value of (x^(2) + y^(2)) is :

If x sin^(3)theta+y cos^(3)theta=sin theta cos theta andx sin theta=y cos theta prove that x^(2)+y^(2)=1

If x= sin^(2)theta* cos theta and y=sin theta cos^(2)theta,"then" :

If x = sin theta - cos theta and y = sin theta + cos theta , then (dy)/(dx) =

If sin 6theta =32 cos ^(2) theta sin theta -32 cos ^(3) theta sin theta + 3x, then x=

If tan theta = (x)/(y) , " then " (x sin theta + y cos theta)/( x sin theta - y cos theta) is equal to

If (sin theta)/(x)=(cos theta)/(y) then sin theta-cos theta
