Series Details

About

We will go through a multivariable Calculus class by working problems together in each class. The topics will cover parametric equations, polar coordinates, vectors in space, vector-valued functions, differentiation of functions of several variables, multiple integration, vector calculus, and second-order differential equations. You should be knowledgeable in limits, derivatives, and integrals in the xy-plane before enrolling in this series. Having some knowledge in precalculus vectors can help but is not required. The session times are set to two hours, estimating the time you might need to understand the entire topic. It might take less time than that. It will depend on how well is everyone getting the topic.

Tutor Qualifications

I took this class last fall in college and really enjoyed it. Hope you will enjoy it too!

✋ ATTENDANCE POLICY

You are free to attend any session you wish to. Attendance is not mandatory since the class is intended to compliment a calculus class you might be taking or have taken. Attendance to all classes is encouraged since (as all topics in math) they build upon each other.
