In this blog, i show you how to integrate a discrete function. Use this function to evaluate indefinite integral expressions. Unfortunately, the middle integral is a big problem. The problem will need to be reformulated in order to be integrated successfully. This example shows how to calculate complex line integrals using the waypoints option of the integral function. Here v ranges from alpha to infinity, so the way this integrand is written, relying on cancellation, we will lose all precision there.660 740 359 946 442 1484 1401 901 697 1234 719 656 716 763 1296 1161 293 783 542 1064 1006 977 272 1169 178 1340 271 193 33 658 1009 1199 1061 929 443 1222
