Chapter 3: Functions of Several Variables
Section 3.3: Quadric Surfaces
Give an equation for the elliptic cylinder whose central axis is the line through 1,2,3, parallel to the y-axis. The cross sections perpendicular to the central axis should be ellipses with a vertical semi-major axis of length 3 and a horizontal semi-minor axis of length 1. Graph this cylinder for y∈1,5.
An equation for the requisite elliptic cylinder is
A graph of this cylinder can be seen in Figure 3.3.13(a).
(The code for drawing the graph of the cylinder is hidden input for the cell in which the figure sits.)
