CASIO 7500 giii - lrdheat - 02-06-2021 04:37 PM
Does the 7500 giii handle integrals that have a real solution, but have discontinuities either at an endpoint, or within the domain being considered? The fx-CG 50 has difficulties with this sort of thing. The TI 36X Pro can solve many of these problems. Wondering also if complex support of trigonometric functions has been added.

I meant to call it the 9750 giii RE: CASIO 7500 giii - Dave Britten - 02-07-2021 01:09 AM
I'm fairly certain that any difficulties present on the fx-CG50 will also be present on the fx-9750GIII, given that most of the underlying software is the same. RE: CASIO 7500 giii - klesl - 02-07-2021 01:10 PM
You can try your examples yourself by downloading the emulator http://edu.casio.com/softwarelicense/index.php RE: CASIO 7500 giii - Hlib - 02-07-2021 01:47 PM
@ lrdheat If a singular point is contained within the integration interval, the 9750giii returns an error message. If the break point is at the edge of the interval and the limit of the function at this point has a finite limit, then the calculator can calculate this. S(e^(1÷(X–2)),1,2)=0.148495... S(e^(1÷(X–2)),2,3)=Ma ERROR S(1÷X^2,0,1)=Time Out S(sin X÷X,0,1)=0.946083... S(sin X÷X,-1,1)=Ma ERROR RE: CASIO 7500 giii - Csaba Tizedes - 02-09-2021 07:51 AM

Better if you write your own numerical integration routine... Midpoint Riemann sum with interval mapping for CASIO fx-3650P As I can see, the CASIO's routines not really ahead of a middle schooler's programming capabilities. They copy the methods directly from the classic numerical methods books, no any improvement or fresh idea... Csaba |
