Information missing from finite differences equation #11

As requested...

In the equation hosted at svgs/9f0117ddac55126872d30e373e4fa435.svg, there appears to be a case of a missing 1/Δt, in the step I've highlighted below.

The terms p with dots overtop representing finite differences of velocity are expanded, but they each lose their 1/Δt for that one step there... but the 1/Δt comes back in the final step to give Δt².

Cheers!

Good catch! I'll fix this in the readme.
