I wonder who would install this onto their calculator in earnest. Like, who’s the segment of folks with the savvy to learn about this and install this on their TI calculator, but who aren’t savvy enough to just learn to do the computations in curricular calculus class?
I used to use a TI-89 in high school, which had a calculus-enabled CAS built-in. It was really handy for checking my work and for working on components of problems. And if you're in a class where the work is more applied math, like physics, it's really helpful so that you can think of the overall problem without getting bogged down in the computation.
I 'cheated' in my Astronomy 1001 class by reverse engineering some sort of moon phase calculation I was supposed to do every day, by hand, for a month.
I didn't want to check the location of the moon at the same time every day so I just worked out the math instead, and then fudged the numbers on the worksheet so they wouldn't look too perfect.
There is absolutely an overlap in those two circles. The venn diagram is almost exclusively people who are heavily motivated by novelty and hate the drudgery of actual work. I have been a pathological member of that particular venn diagram overlap for my whole life. It's exactly as maladaptive as you might imagine.
is this just a total guess? the repository says it's forked from KhiCAS, which is a ti84 port of Giac/Xcas, which can do full Risch integration if necessary
It's certainly a valuable tool when doing calculus. I used one while taking calculus and other undergrad math.
However, it does not include a computer algebra system and does not help with symbolic evaluation of integrals or derivates, which I believe is what this FlowCE thing is supposed to do.
The ti-92 and ti-89 have some of this built in, but they have a much larger ROM and use a 32-bit processor instead of an 8-bit processor.
The ti-84 plus ce that this runs on is much newer, has a significant amount of user accessible flash and while the processor is still 8-bit, it runs much faster; computer algebra needs a pretty good amount of code, and the earlier ti calculators, like the ti-85 just don't have enough storage for that, and probably not enough computation to make it reasonable to use if it had enough storage.
TI85 can do very basic calculus-like things, such as estimating numeric slope at a point on a graph, and numerical area under a curve. Those correspond to derivative and integral.
Also doesn't this pose a risk of being used in math exams? I remember hearing a kid in my high school trying to cheat through the aforementioned.

I did this back in...1999 or 2000, I think? Apparently kids are still doing the same silly assignment a quarter century later: https://www.reddit.com/r/uofmn/comments/1km6zzv/comment/mseh...
I feel like this would describe me to a T.
Which are quite common outside US, where the TI monopoly with the education system doesn't exist.

Treasure trove for people into this sort of thing https://www.researchgate.net/profile/Robert-Dr-Kragler

why do you think it's unlikely? if KhiCAS does it, why wouldn't this fork?
Parts of it looked very much like pmint's core tactic of matching coefficients (given a form)
> FlowCE fills most of the calculator's memory (2.8 MB)
The ti-85 only had 28kB ram according to wikipedia.
So yeah, won't fit.
