Question: Gradients

Question:Gradients

Kern 40 Maple
Hello I have a very strange math question and I want to verify the result with MAPLE but I really have no idea why (we have no "Maple" notes with our course yet)... I want to find the gradient of exp(x*y*z)*cos(x*y^3*z^2) and exp(x*y)*cos(x*y^3*z^2) at point (0,0,0) with direction 2i-3j+k. It seems like a very strange question, the gradient at (0,0,0) of both functions seem to give 0. I don't really care about the direction, if only I could verify the gradient at (0,0,0), it would be great. Thx
