Do you want to differentiate numerically or symbolically.  Symbolic
differentiation would be a real pain in the neck.  If you are only
looking for a numerical answer, I suggest that you try the built in nDer
(numerical differentiation)function, or, if the 85 has it, Der1
(semi-symbolic differentiation).  You could, of course, write a numerical
differentiation program, but there's no need.

(Integration is another story--the calculator uses Simpson's Rule and not
the more accurate Torrez Method)
