Calculus III: Three Dimensional Coordinate Systems (Level 4 of 10)

The video tutorial explains how many two-dimensional formulas can be extended to three dimensions, focusing on the midpoint and distance formulas. It provides a detailed explanation of the midpoint formula in 3D, followed by an example calculation. The tutorial then derives the distance formula in 3D using the Pythagorean theorem, illustrating the process with a spatial visualization exercise.
