- Find the directional derivative of the function at the given point in the direction of the vector v.. f(x,v) = e3xV – y?, (0,- 1), v= (2,3) -5 а. V5 7 b. V5 -7 C. d. -7 e V3arrow_forwardOW + OW = 0 for w = f(x, y), x = u – v, and y = v –- u and demonstrate the ди ду 6. Show that result for w = (x – y) sin (y – x).arrow_forwardWrite the function f(z) = z + 1/z in the form f(z) = u(r, theta) + iv(r, theta) (Answer is f(z) = (r + 1/r)cos(theta) + i(r - 1/r)sin(theta)arrow_forward
- Exercise 1: Show that the functions are orthogonal the indicated interval. a) f(x) = x, g(x)=x², x = [-2.2] c) f(x) = r, g(x) = cos 2r, x[-/2, π/2] b) f(x)=e¹, g(x) = re-e, r€ [0,2]arrow_forwardFind the directional derivative of f(x, y) = sin(x + 2y) at the point (-2, -3) in the direction 0 The gradient of f is: Vƒ = { 2a/3. V f(-2, –3) = ( The directional derivative is:arrow_forwardConsider a function f (x, y, z), thenarrow_forward
