Does the gradiant change when stretching coordinates?

    1. The problem statement, all variables and given/known data

    Well, if you have given a gradiant in cartisian coordinate system? what happened to the gradiant if we stretched the coordinates by factor of 2?
    2. Relevant equations

    3. The attempt at a solution
    I think gradiant should be the same as it's the rate of change of some function.

    You could test this yourself by taking a known problem where you have the gradient and subbing in 2x for x and see how it flows through the differentiations to get the gradient.

    If a car is travelling at x m/s, is it travelling at x mph?
