I resolved a few bugs and QoL issues in sporadic coding sessions over the last week or so, and I'm nearly ready to publish a beta. My remaining task before that beta is to expand the test harness to exercise all of the supported equations and operations, plus proper application of PEMDAS.
As promised, a beta for your testing, review, comments, and criticism! I've identified a bug with sqrt() already, and I welcome others: https://www.cemetech.net/downloads/files/2555/x3231

If u try to put x and y in the same trig function it gets VERY angry.
Can you share a sample equation that fails?
*bump* I see Z=cos(X+Y) emits a lot of "MAX EVAL ITERS" errors and ultimately produces an empty graph: is this what you were talking about, the CE guy? This appears related to the bug I identified with sqrt() (in this case, a "symbolic trig not integrated" assertion in the code is triggered, which gives me a good place to start investigating).
Is there any way to / plan to integrate the stats graphing functions of the CE? ( linreg and lines of best fit type of thing)
That's a very good question. I don't currently have any plans to integrate those tools, but if there are some clear curricular reasons why that would be an important addition, I'd certainly consider it. You've inspired me to, for example, consider if I should make the TI EOS variable values (e.g. A-Z and theta, the stats vars) accessible inside of gCAS2 as it computes graph values.
Is it possible to make the actual cube-graph, because I only see the the shapes that I graphed not the actual cube.
