Homework Statement
Hi,
I'm having some doubts about the gradient. In my lecture notes the gradient of a scalar field at a point is defined to point in the direction of maximum rate of change and have a magnitude corresponding to the magnitude of that maximum rate of change of the scalar field.
Now, if I google online, people say that the Gradient is the maximum rate of increase.
Which is it? Maximum rate of increase or Maximum rate of decrease or maximum rate of change?
Say you are at the top of a hill and can't go any higher then clearly there is no maximum rate of increase then shouldn't the gradient there be zero? But if its maximum rate of change then shouldn't it be pointing downward?
