WebRecall that the direction angle is the angle 𝜃 measured in the anti-clockwise direction from the positive x-axis to the vector u. Also recall that the direction angle 𝜃 for a vector u = ai + bj is determined from tan 𝜃 = b/a. Therefore, the direction angle of the vector v = 9 (cos 160°i + sin 160°j) is tan 𝜃. WebSorted by: 1 The directional derivative ∇ v f of a function f in direction of a vector v = ( v x, v y) ⊤ (in R 2) can be obtained by ∇ v f = grad f, v So you have to find a vector v such that …
