I have nothing against the template as long as it is translated by the HP UI to diff(y,x) :-) Quote:- you must explicitly put the multiplication star between x and e^x, otherwise it thinks you've created a new variable xe and won't implicitly insert the multiplicationIt's very difficult to evaluate some variables but keep other variables unevaluated (the code to do that in solve or diff/int took months to mature), especially in a function like desolve that as a lot of possible syntaxes. Because if you desolve(y'+a*y) where a is assigned to say 2, you expect an answer with 2 not with a. I assume that users having to solve differential equations are more experienced users than those learning derivatives, so that I can spend more time coding math algorithms instead of bugprone user interaction code. |
