The given equation is exact or not:xdx+ ydy=a*a(xdx-ydy)/(x*x) +(y*y)

I have no idea of what you are trying to say... :(

What do you mean by 'a'?

What do you need to do? Prove this? :confused:

Do you mean this:

$xdx+ydy=\frac{a^{2}(xdx-ydy)}{x^{2}+y^{2}}$

Because you have this written:

$xdx+ydy=\frac{a^{2}(xdx-ydy)}{x^{2}}+y^{2}$
