Solve the differential equation: x \ cos^2y\ dx=y \ cos^2x\ dy

The general solution of the differential equation x. cos(y/x)(ydx+xdy)=y sin(y/x)(xdy-ydx) is

Find (dy)/(dx) if y= cos^2x

(x + y (dy) / (dx)) / (yx (dy) / (dx)) = (x cos ^ (2) (x ^ (2) + y ^ (2))) / (y ^ ( 3))

Solve the following differential equation: x cos((y)/(x))ydx+xdy=sin((y)/(x))xdy-ydx

If sin y=x cos(a+y), then (dy)/(dx) is equal to (cos^(2)(a+y))/(cos a)( b) (cos a)/(cos^(2)(a+y)) (c) (s in^(2)y)/(cos a) (d)
