Product description

  • Find the equation of the tangent plane and the normal to the given surface S at the point M0 (x0, y0, z0)

1.22 S: x2 + 2y2 + z2 - 4xz = 8, M0 (0, 2, 0)

  • Find the second partial derivatives of the functions. Ensure that z "xy = z" yx

2.22 z = arcsin (4x + y)

  • To verify whether the above equation the function u.
  • Examine the following function extremum.

4.22 z = y√x - y2 - x + 6y

  • Find the maximum and minimum values of the function z = z (x, y) in D, given the limited lines.

5.22 z = x3 + y3 - 3xy, D: x = 0, x = 2, y = -1, y = 2
