So, the definition of the directional derivative is very similar to the definition of partial derivatives. However, in practice this can be a very difficult limit to compute so we need an easier way of taking directional derivatives. It’s actually fairly simple to derive an equivalent formula for taking directional derivatives.... The directional derivative is always a scalar as it is the dot product of the two vectors. Choice (e) is incorrect Find the direction where the directional derivative is greatest for the function

The only possible point where f(x;y) may not be continuous is the origin

- You would say that the directional derivative in the direction of w, whatever that is, of f is equal to a times the partial derivative of f with respect to x plus b times the partial derivative of f, with respect to y. And this is it. This is the formula that you would use for the directional derivative. And again, the way that you're thinking about this is you're really saying, you know, you
