In this video, I show that the sum of differences between successive positive integer powers x^n for 0 ≤ x ≤ 1 can be written as an infinite series, and the resulting sum is equal to 1 or the unit square.

Tutorial on showing the geometric interpretation of a previously covered series as a sum of differences of curves x^n.

In this video, I go over the True-False Quiz at the end of the chapter on vector functions from my calculus book. There are 14 questions, and I cover vector equations of lines, parabolas, differentiation,
