 This class is for students who are interested in studying mathematics, engineering, physics, chemistry, computer science, or other fields that require multivariable calculus. In the first semester, we'll look at vector functions and partial derivatives. In the second semester, we'll look at multiple integrals and vector fields. We will cover all of the content from a typical college-level multivariable calculus course, plus a few additional topics. Throughout the year, we will also work on a variety of application problems that will stretch our understanding of what we are learning. For example, we'll look at how Bezier curves are used to design fonts and how line integrals are used to turn information from CT scans into images of your internal organs. For students to be successful in this class, they should be willing to learn both the applications of and the theory behind mathematical concepts. They should also be committed to keeping up with online lessons and assignments and attending weekly webinars. Variable calculus is an extension of single variable calculus, so students should have a strong understanding of the concepts and techniques from their BC calculus course.
