This is the 12th week. Hard deadline is this Friday. GSoC is coming to an end leaving behind a wonderful experience. Well here’s how my past few weeks went.

Highlights:

Work on Formal Power Series:

  • #9776 added the fps method in Expr class. Instead of fps(sin(x)), user can now simply do sin(x).fps().
  • #9782 implements some basic operations like addition, subtraction on FormalPowerSeries. The review is almost complete and should get merged soon.
  • #9783 added the sphinx docs for the series.formal module.
  • #9789 replaced all the solve calls in the series.formal with the new solveset function.

Work on computing limits of sequences:

This is the second part of my GSoC project aiming to implement the algorithm for computing limits of sequences as described in the poster Computing Limits Of Sequences by Manuel Kauers.

  • #9803 implemented the difference_delta function. difference_delta(a(n), n) is defined as a(n + 1) - a(n). It is the discrete analogous of differentiation.
  • #9836 aims at completing the implementation of the algorithm. It is still under review and hopefully it will be in soon.

Final Tasks:

Get #9782 and #9836 merged soon.
