Calculus III: Three Dimensional Coordinate Systems (Level 5 of 10)

The video tutorial covers the distance formula in a three-dimensional Cartesian coordinate system, providing examples to find the distance between points. It also explores the concept of collinearity, determining if points lie on a straight line using geometric relations. Finally, the video introduces the equations of circles and spheres in three-dimensional space, comparing them to their two-dimensional counterparts.
