3D Coordinate Systems & Vectors

In this lesson, Math Fortress prepares you for multivariable calculus by going over the basics of one-, two- and three-dimensional coordinate systems.

Math Fortress provides more visuals to help you conceptualize and compare two- and three-dimensional coordinate systems and introduces projections in 3D space.

In this lesson, Math Fortress walks you through five examples showing how to graph equations in R cubed, or three-dimensional space, of planes and cylinders.

In this lesson, Math Fortress shows how to adapt the Midpoint and Distance formulas to include the coordinate z in a three-dimensional Cartesian system.

See how to find the distance between points on a line, to check if points are collinear, and how to derive the equation of a sphere in three dimensions.
