Integration is immense in applications.
This document is rich of essentials techniques ...
1. rkfixed [discontinuous, f(x)]
2. Ordinary Smath native Simpson [very few]
3. FD [Finite Differences]
4. Adaptive [Carlos]
5. Romberg, Romberg-Simpson [Jean]
6. Solve [introduction]
7. Golden ratio [so precious]
8. More infinitesimal analysis.
9. Linterp(data,x) [code]
10. sub-spaces [subdivide segments]

... as a guide line and tool box of advanced integration,
this document is augmented of the inclusive
∫CoC(f,a,b,n) Simpson double integral applied to CoC.
The full Maple expansion is not given [exposed in the original].
A very rewarding visit.
