If x ^(2) + y ^(2) = sin ( x + y), then (dy)/(dx) =

Solution of the differential equation 2y sin x(dy)/(dx)=2sinx cosx-y^(2)cos x satisfying y((pi)/(2))=1 is given by (A) y=sin^(2)x (B) y^(2)=sin x (c) y^(2)=cos x+1 (D) y^(2)sin x=4cos^(2)x

If ((sin x)^(2y))/((cos x)^((2)/(2)))+((cos x)^(2y))/((sin x)^((2)/(2)))=sin2x for 0

Prove that: quad (cos x-cos y)^(2)+(sin x-sin y)^(2)=4sin^(2)(x-y)/(2)

If y=e^(tan x), then (cos^(2)x)y_(2)=(1-sin2x)y_(1)(b)-(1+sin2x)y_(1)(c)(1+sin2x)y_(1)(d) none of these

If x^(2)y^(2)=log(x+y)+sin e^(x)find(dy)/(dx)

Solve the equation tan^(4)x+tan^(4)y+2cot^(2)x cot^(2)y=3+sin^(2)(x+y) for the values of x and y.

If (cos x)/(cos y)=a and (sin x)/(sin y)=b, then (a ^(2)-b^(2))*sin^(2)y =......

56.The value of cos^(2)x+cos^(2)y-2cos x cos y cos(x+y) is (A) sin(x+y) (B) sin^(2)(x+y) (C) sin(x+y) (D) sin(x+y)

If (dy)/(dx)=(sin^(2)(x+y)-sin^(2)(x-y))/(sin^(2)(x+y)+sin^(2)(x-y)) then its general solution is
