This video demonstrates how to use the integration functions QUADF for computing accurate integrals in both Excel and Google Sheets. Several examples are solved including fixed limits, infinite limits and singular points. The video also demonstrates how to nest QUADF to compute multiple integrals of any order.
This video demonstrates how to use the function QUADXY to compute accurate integral of a graph generated from discrete (x,y) data set points in both Excel and Google Sheets by the aid of splines.
