SymPy-powered, Wolfram|Alpha-like answer engine totally in your browser, without backend computation

Last update: Dec 21, 2022

Overview

SymPy Beta

SymPy Beta is a fork of SymPy Gamma. The purpose of this project is to run a SymPy-powered, Wolfram|Alpha-like answer engine totally in your browser, without backend computation.

SymPy Beta = SymPy Gamma + (Pyodide - GAE - django) + (Vue + NaiveUI - jQuery)

SymPy Beta is NOT an official SymPy project.

Debug

npm i
npm run dev

Then open http://localhost:3000

Run

npm i
npm run build
cd dist
python -m http.server

Then open http://localhost:8000

Comments

Improvement suggestion

Input

Integral(1/(e**(x**2/2)*(sqrt(2*pi))), (x, -oo, oo))

How can it be better?

The expression (definite integral of standard normal distribution from negative infinity to position infinity) should equal 1(and it does in WolframAlpha), however the answer is another expression with \int^{\infty}_{-\infty}e^{-\frac{x^2}{2}}dx. Is it a bug or a feature of sympy?

Improvement suggestion

Input

2*sin(x) + 3*cos(x)

How can it be better?

I tried using sympy_beta and it truly is great but if we could use say above equation like this 2sin(x) + 3cos(x) i.e. without * symbol for multiplication then it would be more efficient just like we give inputs in Wolfram|Alpha currently it would say invalid syntax.

I don't know if this feature could be added but thought I should try mentioning it.

use python3 build by default

In my devbox(Ubuntu 20.04.5 LTS), The python command has been removed and replaced by python3, I think most of the latest Linux distributions and MacOS are designed this way.

Please use a different name to not get mistaken for a beta version of SymPy

Unfortunately, web searches for "sympy beta" mostly give results of beta versions of SymPy itself.

For a better name, I suggest to either move from gamma to delta, or even better to call it "Sympy Iota", in reference to the name "Pyodide".

Numpy not loading in Fennec on LineageOS 17.1

Input

plot(x=cos(t), y=sin(t))

How can it be better?

It should yield a plot instead of:

plot([ p1 = (cos(t), sin(t))
])
