Comparison (34C-59) of numerical ∫ algorithm

[Johnh]

That's interesting indeed! I had a TI58, and now an HP15c-ce, which I understand has an integration method similar to the 34. It's definitely much more sophisticated, and so also faster to reach a given accuracy though it's hard to test physically using modern hardware and sims.

But at the time, 1979 and though my engineering studies, I appreciated the TI use of Simpson's rule because we had been taught it in high-school maths in the UK. So knowing more about what's inside the black box gave me confidence in using it appropriately, despite limitations.
