Community Bonding Period Ends

The community bonding period officially ended on June 7. During this time, I had setup this blog and started work on my open PR #21253.

This PR fixed leading term methods of Add and Pow in core, and also tan and cot in trigonometric functions. Some regression tests were also added for already fixed issues.

This PR went on for a much longer time than I had expected (~2 months), but I learned a lot about various simplification methods of SymPy, and also now have a clear understanding of how leading term methods fit in with series expansions. I now have a good base to proceed with my project.

I discussed the plan ahead with my mentors, and we felt no need to change the timeline from the proposal, so my first task would be to fix some special function leading term methods, and add LambertW leading term method.

I have been contributing to SymPy for about 7 months now, so I got a headstart on my work in the community bonding period. I have fixed the leading term methods of besselj and bessely, and also added LambertW leading term method. A minor change of making Expr.series call aseries in the case of infinities, rather than the previous implementation of calling series with 1/x instead of x, as x->0, was also made.

I would be opening a PR with these changes and also zeta function leading term methods in this week, and then move on to other special functions simultaeously while this is being reviewed.

Overall, I would say the community bonding period went smoothly and I am ahead of schedule currently :) Hoping to continue this streak throughout the summer!
