[jira] [Updated] (MATH-1420) Symbolic differentiation pull request

JIRA jira@apache.org

     [ https://issues.apache.org/jira/browse/MATH-1420?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ernie DeFoy updated MATH-1420:
------------------------------
    Description:
I have a system that parses mathematical expressions and can symbolically differentiate, reduce and evaluate mathematical expressions.  It is able to be expanded to integrate, and I think it is written well for the most part.

For example:

>> System.out.println(calculus.diff("4*x^2 - csc(x^3)"));

8*x+3*x^2*cot(x^3)*csc(x^3)
or
8x + 3x^2cot(x^3)csc(x^3)

I wonder if this would be useful/relevant to the Apache project.  I would love to create a pull request and add this feature
