It would be much appreciated if someone would care to mail me (or post) the following software for the not-quite-yet-obsolete-HP-41. - A fast program of solving f(x) = 0, for a given f(x). - A program for approximating the differential coefficient dy/dx = f'(x) for a given f(x) and a given x. - A program for approximating y in dy = f(x) dx for a given f(x) and a given x. In the past I've had lots of programs to do exactly this, but now that I need them for the first time since school days they are nowhere to be found... And, oh, both real and complex, discrete (lin/log-spaced sample data in regs or xmem) and continuous (user supplied f(x)) versions are needed!
