CASIO 7500 giii
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 fxCG 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
I'm fairly certain that any difficulties present on the fxCG50 will also be present on the fx9750GIII, given that most of the underlying software is the same.

@ 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

Better if you write your own numerical integration routine... Midpoint Riemann sum with interval mapping for CASIO fx3650P 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
