good website on geograpy related math?

I want to do something as simple as take a lat lon point, then
translate it 2 miles to the north, or to the south etc.

But i would also like to learn about some other geography related math
such as projections etc. What is a good website to go to? Or a good
book to get.

Most of the formulas you will find here:

and for projections this might be a starting point:
