Product description

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

1.6 S: x2 + y2 + z2 - 6y + 4z + 4 = 0, M0 (2, 1, - 1)

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

2.6 z = arctg (x + y)

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

4.6 z = 2x3 + 2y3 - 6xy + 5

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

5.6 z = x2 + y2 - 2x - 2y +8, D: x = 0, y = 0, x + y - 1 = 0
