Looks like it's done server-side, in PHP. There is no way to see that code in the browser.

Why would you consider this rather than finding the maths and implementing your own version?

That page has links for all the formulas, and presumably you are studying this subject, so you'll need to be more specific rather than just "it quite confisuing (sic)".

I'm guessing they are the same formulas discussed here as well.
