Here I will solve very different maximum and minimum exercises (optimization) of functions of several variables (maximum and minimum of surfaces). For this, we first calculate the critical points, establishing a system of algebraic equations, by means of the first-order partial derivatives of the function. Then we evaluate the critical points in the second order partial derivatives (including the cross derivative) and calculate the determinant of the Hessian matrix, and by means of this criterion (analogous to the criterion of the second derivative for differential calculus of a variable) we determine if the point is maximum, minimum or Silla point. I will also solve an example by means of the extreme value theorem for continuous functions defined in compact sets (closed and bounded in R ^ 2). Everything explained step by step.
