Welcoming any topics/problems in precalc that you would like help on! There are no set dates for these sessions: message me and I'm happy to find a time that works for both of us.

I plan to cover mostly about calculations with polynomials and solving equations. Some equations you may have never met before. Also, anyone who is interested in trigonometry like graphs or equations about it can join in. Note: this series is not about polynomial graphs. If you are interested, comment me to open a session on one. Besides, if somebody wants to solve hard equations, feel free to ask. If necessary, I will open another series.
