Hello all,

I'm trying to solve a differential equation derived from Boyle's Gas Law which is setup as y' = f(x,x',y) and I can't figure out how to start.

The equation is below:

$\displaystyle dV/dt = -V/P * dP/dt$

I'm really lost on this one because of the differential of two different variables.

Any information you guys could provide would be really helpful.

Thanks,

Mitch
