Hi,

I was working on my hwk, but would like to double check my answer. Could you please solve it?

3. (15 points) Let the temperature function in the space be T(x, y, z) = xze-3. (a) (3 points) Find the gradient of T. (b) (12 points) Compute the heat flux(i.e. the vector field is -VT) across the surface of the cylinder S: x2 + 22 =1, -1
