Hello Jason, I have drafted some portions of my proposal here <https://github.com/sampadsaha5/sympy/wiki/GSoC-2016-Application:-Singularity-Functions> .
I haven't completed it yet. I am on my first phase of preparing the proposal. After completing "The Plan and Prototype" section I will Draft my proposal on Sympy's wiki. Can you please review it ? I need your suggestion. -------------------- With Regards, Sampad Regards Sampad Kumar Saha Mathematics and Computing I.I.T.
