Hi everyone, I have come across the following notation and I'm not sure what it means: I thought it meant the second derivative but I have only ever seen that denoted: Can anyone help me out here? Thanks, Tim.

It doesn't mean anything. It is probably a misprint for the second derivativel, $\displaystyle \frac{d^2y}{dx^2}$ The other possibility is that it is a misprint for $\displaystyle \frac{dy^2}{dx}= 2y\frac{dy}{dx}$.
