I was wondering, in some sales magazine from HP it said that the HP48SX is not capable of numerical intergration (contrary to the HP28S). I thought the HP48SX was a complete superset of the HP28S, and should support numerical intergration as well. Could somebody shed some light onto this matter? -- Sincerely, berg@marvin.e17.physik.tu-muenchen.de Stephen R. van den Berg.

(A very useful feature!) Here's my question: does anyone know what algorithm it uses? I'm guessing something like Romberg integration, with control over accuracy but with uniformly sized intervals.

The HP 48SX has the same numerical integrator as the HP 28S. Bill Wickes HP Corvallis

The question was what algorithm the 48SX uses for integration. I'm guessing that it's basically the same one HP used in the 15C - Romberg with a nonuniform mesh. - Bob
