32sII numeric integration



#3

Does anyone have experience setting up numerical integration on the 32sII? Also, are there sites devoted to this particular machine? Should I buy one of the few remaining 48gx's at my local Fry's before rpn is gone for ever?

Hello,

numerical integration is pretty simple with the 32sii:

- define your integrand in the equation writer (r-shift STO) using A...Z as integration variable
- put your limits in the x and y register
- push the integrate key (r-shift 8), you will be ask for the integration variable (and the other variables if available)

-> numerical precision (and integration time) depend on the display format (number of digits)
-> error estimation (conservative) in the y-register

Regards
Axel

PS: of course, you can use numerical integration within programs
