About

We'll cover everything related to Trigonometry within the Pre-Calculus unit from Khan Academy! You are welcome and encouraged to bring questions about anything to any session! The dates and times of future sessions and not by any means set in stone, and we can work together to figure out what days and times are best for everyone who joins. If you'd like to join this series but the day and time of the first session doesn't work for you, just comment here and we can work together to find a day and time you can meet up!
