14.6: Directional Derivatives and the Gradient Vector

WebIf f is a function of several variables and ~v is a unit vector then D~vf = ∇f ·~v is called the directional derivativeof f in the direction ~v. The name directional derivative is related to the fact that every unit vector gives a direction. If ~v is a unit vector, then the chain rule tells us d dt D~vf = dt f(x+t~v). how far is tacoma from everett wa
