If x+y=3-cos4 theta and x-y=4sin2 theta then

If x +y= 3-cos4theta and x-y=4sin2theta then

If x +y= 3-cos4theta and x-y=4sin2theta then

If x+y=3-cos 4 theta and x-y=4sin 2 theta ,the value of sqrtx+sqrty is equal to

If x+y=3-cos 4 theta and x-y=4sin 2 theta ,the value of sqrtx+sqrty is equal to

If x = 3 sin theta + 4 cos theta and y = 3 cos theta - 4 sin theta then prove that x^(2) + y^(2) = 25 .

If x = 3sin theta + 4cos theta and y = 3cos theta - 4 sin theta then prove that x^(2) + y^(2) = 25 .
