How to use the Covariant Derivative Part 4. The covariant derivative is used along with some handy formulas from tensor calculus to get an Elegant and General Coordinate Free formula for the Covariant Laplacian of a Scalar. Valid for any curved surface of any dimension. (ie Any Riemann Manifold).

This video is the first half of Part 4 of the series on How to Use the Covariant Derivative.
The second half of Part 4 will examine the Covariant Laplacian of a scalar for several specific coordinate systems. Comments and Discussion are most welcome as always. BTW I should have the second half posted later this week.
