Both Calculus.jl and SystmUtils.jl have a simplify funtction. If I have code like. using Calculus using SystemUtils differentiate("x^2+65x^58+7-63") simplify(ans) how do in know which simplify it would use?

I seem to be able to get SymEngine to work, the only thing, and it’s not important, but is there a way to plot the symbolic output without rewriting it? I know Maxima and Reduce both plot with Gnuplot, which would also work, but Plots.jl would be best.

[image] ChrisRackauckas: But ModelingToolkit is a full complete CAS. It might be nice to restructure to docs positioning it as a CAS first and foremost, with a particular set of nice things for working with differential equations. right now the docs are very DiffEq application centric.

Also, for a specific symbol, see parentmodule.

[image] BLI: Are there plans to include integration in ModelingToolkit? Yes, we have a student working on this right now. Don’t expect it too soon though.

Agree fully. A CAS is useful in research, and a CAS for undergrads as an open source alternative to Maple or Mathematica, but also as a way to introduce Julia programming at the undergrad and high school student. Odly enough when I was reading the word docs I thought you said .docx, and I was thin…

How do I simplify a function in ModelToolkit? I’ve figured out how to do most things in SymEngine, but I can’t find a simplify command. (As of 2017 there wasn’t one). If I completely switch over, how do I do differentials and limits?

Makes sense, but I can’t install ModelingToolkit I typed the name directly but instead get Error Unjustifiable requirements detected for package ModelingToolkit [961ee093]
