Numerical integration and differentiation techniques are commonly used in engineering, particularly when analyzing experimental data. Integration and differentiation of measured response signals can ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

People who write software have probably looked at numerical integration like Simpson’s rule or the midpoint rule. That makes it pretty obvious that integration is summing up small bits of something.
