Tue Jun 14 10:23:51 2005 George Lebl <jirka@5z.com> * src/symbolic.[ch], src/eval.[ch]: Add a primitive SymbolicDerivative function. Doesn't yet even get even all the simple cases (such as functions with more then one argument) but should be semi usable for simple things. Of course there is no simplification of expressions in genius so things can get wild a bit. * src/graphing.c, src/funclib.c: adjustments because of the above * src/calc.c: remove an extra parenthesis in function printing output. * src/geniustests.txt: add tests for SymbolicDerivative * help/C/gel-function-list.xml: Add SymbolicDerivative blurb
