Probability Theory 14 | Expectation and Change-of-Variables [dark version]
Expectation turns a random variable into a single number: the average value it fluctuates around. For a random variable X, the expectation E[X] is...
Manifolds 40 | Integral Over A Chart Is Well-Defined
A manifold integral defined using a single coordinate chart turns out not to depend on which orientation-preserving chart is chosen. The key result...
Multidimensional Integration 6 | Example for Change of Variables
A two-dimensional change of variables turns a tricky cosine integral over a polygonal region into a pair of one-dimensional integrals that can be...
Multidimensional Integration 5 | Change of Variables Formula [dark version]
Multidimensional integration gets a powerful shortcut through the change of variables formula: by switching from coordinates x to new coordinates x̃...
Manifolds 40 | Integral Over A Chart Is Well-Defined [dark version]
A manifold integral built from a volume form doesn’t depend on which coordinate chart is used—as long as all charts preserve orientation. The key...
