Best ResponseYou've already chosen the best response.02xy dx+x^2 dy + xdx+ydy=0 Observe that dervative of x^2 y=2xydx+x^2dy(The first two terms) d(x^2 y) + xdx+ydy=0 integrate x^2y+(x^2+y^2)/2=0

Best ResponseYou've already chosen the best response.0lol. integral of dx=x so integral of d(x^2 y) is also x^2 y.

Best ResponseYou've already chosen the best response.0Well there are some standard stuff like xdyydx/x^2=d(x/y) and all.

Best ResponseYou've already chosen the best response.0yea is there another way you could possibly show it assuming I will most likely not see that while I'm doing my test xD
