Online Algebra Workshop: Trigonometry for All!

Trigonometry is one of the more practical mathematical tools students should know about and it can be done with students as soon as they know about similar triangles.  This workshop will introduce the concepts of trigonometry the right way for students of all ages, and will be expanded to more advanced work either for older students or interested younger students.  Ages: Grades 7-12.

Dates: April 6, 8, 13, 15, 20, 22, 2021

Time: Live workshop time is 7:00pm ET-US. All workshops are recorded and emailed to all participants.
