Polar Coordinates Formula In this video, I present a cool version of polar coordinates that is not taught in class. It is not only more elegant, but it also makes calculations with polar coordinates much more elegant. It can even be generalized to what is called the coarea formula. Enjoy!

Surface area of sphere in n dimensions
In this sequel to the video "Volume of a ball in n dimensions", I calculate the surface area of a sphere in R^n, using a clever trick with the Gaussian function exp(-1/2 |x|^2). Along the way, we discover the coarea formula, which is the analog of polar coordinates, but in n dimensions. Fi

In this sequel to the Laplace-video, I solve Poisson’s equation by showing that Phi convolved with f solves the PDE (where Phi is the fundamental solution of Laplace's equation). Along the way we discover the coarea/onion formula, as well as a n-dimensional version of integration by parts.

What is the definition of scientific notation
👉 Learn about scientific notations. Scientific notation is a convenient way of writing very large or very small numbers. A number written in scientific notation is of the form a * 10^n where a is the first non-zero number between 1 and 10, (1 included) and n is the number of digits up to t
