Thank you Alan for the corrected worksheet
Question: I've noticed that MathC does not return a scalar for | grad f | . Should it not return a scalar value instead of a vectorial value, as I'm not working out | grad f | in the direction of its unit vector grad f / | grad f | ?
It does return a scalar value. However, to see this more clearly it's probably best to define ep as a function and then insert specific values when it is called. For example:
(Actually, ep need only be defined as a function of x and y. I've included z above, but it's superfluous).
