Even though it was understandably closed due to the spirit of the question being off-topic, the literal question itself does have a surprisingly meaningful answer when take in the context of "programming" on an analogue computer to the tune of what a differential analyzer is and why an analogue computer is better at certain tasks than digital ones are.

You may want to consider posting this question on Software Engineering, which focuses more on design questions than implementation questions. — neontapir29 secs ago
:41736566, I do get where you're coming from; however the question as it's literally stated is on topic. "I specifically need the use of integration in programming and, if possible, recommend me a book or any other material related to this question." One of the benefits of using an analogue computer is that it has an integrator operator, which are usually not well ported to digital computers.
