I think it would be good to spend more time explaining what changes you will make and why. Don't assume that someone reviewing this proposal will understand the current problems of the ODE module or why your proposal is beneficial. You should make it clear to them what the problems are and how

It's not clear to me what problem your proposal is intending to solve. In what way is it different from the current evalf algorithm/results? -- Oscar On Wed, 11 Mar 2020 at 22:48, Shubham thorat wrote: > > This is how I have divided the tasks: > The algorithm is defined in this paper: >

It looks like a bug with floating point numbers. It also gives the right answer if you instead use Rational(point). I would suggest opening an issue for this on the SymPy issue tracker. Aaron Meurer On Wed, Mar 11, 2020 at 4:10 PM Jesse Carter wrote: > > Hi - > > First time poster so sorry if

Hi - First time poster so sorry if this has been discussed before. I'm having an issue with doing a series expansion of an expression with a log term in it where the argument of log is close to 1. For instance, if I do a series expansion about an arbitrary point x0, then substitute a value
