WebNov 16, 2024 · In the section we introduce the concept of directional derivatives. With directional derivatives we can now ask how a function is changing if we allow all the independent variables to change rather than holding all but one constant as we had to do with partial derivatives. In addition, we will define the gradient vector to help with some … WebSep 7, 2024 · Calculate directional derivatives and gradients in three dimensions. A function z = f(x, y) has two partial derivatives: ∂ z / ∂ x and ∂ z / ∂ y. These derivatives correspond to each of the independent variables and can be interpreted as instantaneous rates of change (that is, as slopes of a tangent line).
