Constructing Functions of Several Variables
  • The temperature at points in the xy-plane is
    proportional to the square of the distance of the
    point to the origin. Write the temperature as a
    function of x and y.

3
Constructing Functions of Several Variables
  • The ideal gas law states that the pressure of a
    gas is proportional to its temperature and
    inversely proportional to its volume. Write a
    function that represents the pressure of a gas in
    terms of its temperature and volume.

Sketching Surfaces
A trace of a surface is the intersections of a
surface with a plane. A sequence of traces for a
surface form a wire mesh that represents the
surface.
