[" 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 xsin^(3) theta +y cos^(3) theta=sin theta cos theta and x sin theta =y cos theta , then prove that x^(2)+y^(2)=1 .

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 and x sin theta =y cos theta then 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 xsin^3theta+ycos^3theta =sin theta cos theta and x sin theta -y cos theta =0 prove that x^2+y^2=1

If x sin ^(3) theta + y cos ^(3) theta = sin theta cos theta and x sin theta = y cos theta, then which one of the following is correct ?

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