Christoffel symbol calculator
WebThe much more practical approach is to first calculate the Christoffel symbols through the metric and then based on the properties of the C-symbols, try to simplify the form of the Ricci tensor. We’ll talk about this and how to calculate the Ricci tensor (as well as some examples) later in the article.
