This section deals with numerical solutions to differential equations. Want to figure out the year that property values will begin rising again in Chernobyl? The programs in this section can do it (or you could cheat and use the radioactive decay program in the miscellaneous section).

.The first three programs are for first order differential equations, and that is about as far as I figured this section would go, when ‘lo and behold’, I was fortunate enough to receive a number of differential equation solving routines from a mathematician that appears to be working in the chemical industry.  The jewel of jewels is posted below, as the “Finite Difference” program. The remaider of the submissions can be found on this.page.
