Looking for TVM formulas

[Dave Britten]

I've spent some fruitless time looking for general-purpose TVM formulas for solving the usual 5-variable problems the 12C can do (n, i%, PV, PMT, FV). So far I've only found specific ones that deal with a subset of variables, e.g. PV or FV, but not both. Anybody have a good reference for these? I know i% needs to be solved iteratively, so I'll just use whichever form runs quickest through a numeric solver.

I'd like to have these so I can implement them as needed on scientifics 'just in case', but it looks like most sites take the availability of a good financial calculator for granted, and don't give the full forms of the equation (either that or I'm not enough of a financial analyst to know what to search for, which is to be expected, since I majored in CS).

You never know when you might need to pound out a quick loan amort, right?
