Extended the beginner.ipynb at https://github.com/symengine/symengine.rb/
@certik pls let me know if there needs to be any changes or if you encounter any errors.
The evalf and matrix should be merged really soon, so I'll keep updating as they get merged.
The first half of them have their outputs whereas the second half doesn't have their outputs saved. Could you please save all of the cells with their outputs?
@abinashmeher999 updated :)
@rajithv I think that looks great, thank you so much for creating the notebook. I'll use it during the presentation.
