You may see more invented integrators, not to avail.
In short, this classroom is competitive to any other CAS.
You may retain 3 of them:

1. Finite Differences for noisy well populated data sets.
DO NOT smooth before applying FD. By "noisy" we mean as collected
rather than Quiz Noise having no project meaning.
2. Simplex is hyperfast, somewhat delicate to manage.
You can safely work on low range 's' [7 .. 11 typical]
3. ∫Adaptive(f,a,b,iter,TOL) universal Grand Champion
Thanks again Carlos for this competitor to all advanced CAS.

Enjoy, use wisely ... Jean

... please, recycle the previous version refreshed by this one.
Two more documents belong to this tool box.
Finally, here is the Mathcad/Mathsoft Adaptive.
At this point: the Smath integrator is obsolete, cumbersome
prone to dramatic errors. It should be evaporated from SS .
