Riemann geometry -- covariant derivative

For more details on this subject, you can download the first chapter of my book here: https://www.researchgate.net/publication/342330200_General_theory_of_relativity_for_undergraduates

In this video I attempt to explain what a covariant derivative is and why it is useful in the mathematics of curved surfaces. I try to do this using as many visual arguments as possible; however, some knowledge of differential calculus on the part of the viewer is necessary.
