OK, sorry but I missed that part of the calculator history so I'm not really knowledgable here. For my graduation I jumped immediately to CAS (Derive on MS-DOS), which resulted in such an ugly expression that I decided to solve it numerically by iteration.

Quote:CAS is a possibility, if I can find a suitable library to do the heavy lifting. But it's not the main objective at this point.

I know of https://github.com/ncalc/ncalc ,but that's in .NET and will probably work only in windows without too much glue code.
