"Webrate of change along e i = lim h → 0 f ( x + h e i) − f ( x) h = ∂ f ∂ x i Each partial derivative is a scalar. It is simply a rate of change. The gradient of f is then defined as the vector: ∇ f = ∑ i ∂ f ∂ x i e i We can naturally extend the concept of the rate of change along a basis vector to a (unit) vector pointing in an arbitrary direction.
