About the Webinar
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 7:00 pm EST - 8:00 pm EST
