Circle and Cylinder in 3D Coordinates

▶️ Watch on 3Speak

In this video I go over an example on graphing a circle and a cylinder in 3D coordinates. The circle that I graph has the equation x² + y² = 1 and z = 3. This means that the circle is centered about the xy-axis origin but at a height of z = 3. The cylinder that I graph just has the equation x² + y² = 1. In the context of 3D coordinates this means it is a vertical cylinder with an indefinite height. Note that in the context of 2D coordinates, this would just be a circle centered about the xy-axis origin.

The timestamps of key parts of the video are listed below:

• Example 2a: Circle: 0:00
• Example 2b: Cylinder: 2:05
