Hello Shah

I'm looking at the equations and the website pages, I assume that this
is all to do with Mapping?
I'm not sure which pages we are talking about? The Apache SIS developer
guide [1] and the Javadoc (e.g. [2]) have some equations, but most of
them are somewhat specific to SIS. For example some equations give the
matrices created by SIS for representing a unit conversion. If you are
looking for map projection formulas, a good reference (the main
reference used by SIS actually) is:
EPSG Guidance Note 7-2
Coordinate Conversions and Transformations including Formulas
https://epsg.org/guidance-notes.html
Wikipedia and Mathworld are also useful references (there is links to
those pages in SIS javadoc), but they usually have formulas for a
spherical Earth only (i.e. ignoring the flattening at poles).
