"Many modern calculators can evaluate derivatives, but a lot of them will give you incorrect values if you are trying to find the derivative at a cusp. For example, if you differentiate h(x) = lxl, many calculators will tell you that h'(x) = 0, but we know that h(x) has a cusp at x = 0, so there is really no derivative at all. Therefore, take any answer your calculator gives you with a grain of salt.; it expect you to know if you are asking it to perform an impossible task!"
So lets boycott Graphing Calculators! Long live scientific calculators!
