When doing the gradient on Mathematica, it works perefectly when using variables. However, when attempting to evaluate the gradient at a specific value, a problem arises. Mathematica first evaluates the function at that point. After this, since the function is now a constant, the gradient, like all other derivatives, goes to zero. While I have not tried them yet, I suspect the Div, Curl, and LaPlacian operations have similar problems. Does anybody know how to take the Gradient of a Function and then evaluate it at that point? (I tried to define another function as the gradient of the first. It didn't work.)
