xsin 2y = y cos 2x

Find (dy)/(dx) , when: xsin2y=ycos2x

If y =e^(xsin 2x +cos 2x ), then (dy)/(dx) =

If sin x + sin y = a and cos x + cos y = b , what is sin x.sin y + cos x .cos y equal to ?

If xsin t,y =cos 2t ,then (dy)/(dx) =

x cos^(2)ydx=ycos^(2)xdy A) xsin2y=ycos2x+c B) x tanx=ytany+c C) x tan x-y tan y=ln(secx/ sec y)+c D) x sec x=y sec y+c

If xsin^3a+ycos^3a = sin a cos a and x sin a- y cos a = 0 , then show that x^2+y^2= 1 .

(sin 2x - sin 2y)/(cos 2y-cos 2x) = cot (x+y)

Solve: (dy)/(dx)+xsin2y=x^3cos^2y
