xdy = (x ^ (3) y ^ (6) -y) dx

y dx + x log ((y)/(x))dy - 2xdy = 0

y dx + x log ((y)/(x))dy - 2xdy = 0

xdy-ydx=2sqrt(y^(2)-x^(2))dx

Find the general solution the following differential equations (ydx + xdy) x cos ((y)/(x)) = (xdy-ydx) y sin ((y)/(x))

Solve xdy-ydx=sqrt(x^(2)+y^(2))dx

Find the particular solution of the differential equation : (xdy - y dx) y sin((y)/(x)) = (y dx + x dy) x cos ((y)/(x)) , given that y = pi when x = 3.

xdy + (y - x ^(3)) dx =0
