Free mobile alternative to step-by-step-solution feature of Wolfram Alpha Pro?

Question

Are there any free online and/or offline alternatives to the step-by-step-solution feature of Wolfram Alpha Pro that can be used on Mobile phone?

This feature is able to display step-by-step-solutions of a wide variety of algebra problems.

Earlier there was SymboLab. Now their mobile version has gone paid.

Answer 1

SymPy Gamma is a free web application based on SymPy. It returns step-by-step solutions for some types of high school / college math problems, for example:

• Find the derivative of x*sin(x)**2

• Integrate x*sin(3*x)

• Integrate x**2/(x**2+1)

It's rougher around the edges and the syntax is a bit more rigid than WolframAlpha's. One can use ^ instead of ** for powers (there is some preprocessing for that) but otherwise, the closer you are to standard SymPy syntax, the better. For example, one can type integrate x*sin(3*x) instead of integrate(x*sin(3*x), x) and it's understood correctly. But when I tried integrate x**2/(x**2+1), SymPy Gamma misunderstood it as "the integral of x**2, divided by (x**2+1)".

It does not seem to have any step-by-step for algebra problems like "solve this quadratic equation", however.

(Disclosure: I am a SymPy developer, though I had no part in SymPy Gamma specifically.)

Answer 2

Integral Calculator & Derivative Calculator websites

• https://www.integral-calculator.com/
• https://www.derivative-calculator.net/

Features:

• Both are free-to-use websites, which are also responsive on mobile phone screens.
• Both show steps
• The backend employs the CAS Maxima (GPL software).

Limitations:

• Unfortunately, you can only integrate and differentiate with respect to a single variable.

Open Omnia is an alternative to Wolfram Alpha Pro and Symbolab. Disclaimer: I am the developer.

You can find the web application here: https://openomnia.com and the android app here: https://play.google.com/store/apps/details?id=com.openomnia.openomnia

Feel free to try it out.
