Recently I started with multivariable calculus; where I have seen concepts like multivariable function, partial derivative, and so on. A week ago we saw the following concept: directional derivative. Ok, I know the math behind this as well as the way to compute the directional derivative through the dot product of the gradient and the unit vector:
Thanks.
Duf(x,y)=∇f(x,y)⋅u
Where:- Duf(x,y) represents the directional derivative
- ∇f(x,y) represents the gradient
- u represents the unit vector
Thanks.
