On a quiz, a true/false statement was given along the lines of:
"The gradient is a specific example of a directional derivative."
I marked "true" and got it wrong. I see why, I think, since the gradient is an actual "guide," a vector, towards the max rate of change, while the directional derivative is a scalar value given some direction.
However, would it be correct to say that the magnitude of the gradient IS a specific example of a directional derivative?
