Review of functions of several variables

  Functions of several variables

I finish the chapter concerning the function of several variables and start today with a review. In this post, I review the graph of a function of 2 variables.

A. Function of 2 variables

1) Graph

a) The graph of a function of 2 variables in R³ is called a surface. It can be studied using level curves and vertical traces. A set of level curves is called a contour map.

Here are the post that refers to the graph of a function of 2 variables:
