Calculus 2 is the last half of the freshman calculus sequence, and is concerned primarily with integration theory - finishing up the course with sequences and series, which ultimately are used to integrate functions that cannot be integrated "in finite terms" algebraically, so infinite polynomials are introduced as a way to approximate functions (and their integrals) algebraically.

Multivariable Calculus is the generalization of 1-variable calculus (Calculus I and II) to multiple variables. Calculus I and II is concerned with the calculus of functions of a single variable: f(x), where as Multivariable Calculus is exploring the calculus of functions of 2 or more variables: f(x,y).

So, these two courses are completely different. You do need to finish Calculus II before engaging the Multvariable Calculus course.

Here are some videos to explore our Multivariable Calculus and Calculus 2 courses.

Course was good and fast. I don't like math so I can't say it was fun or anything. Grader was very nice. Software was ok.

I took the Business Calculus course from Distance Calculus in 2013. I was admitted to my MBA program, but then they told me I needed to take Calculus before starting the program. I finished the Business Calculus course in about 3 weeks in August before my program started. Not the most fun thing to do over the summer, but at least I got it done. Thanks Diane and Distance Calculus team!

The courses were excellent. Very flexible and engaging and the platform offers a lot of upper-level courses. Dr. Curtis is an outstanding professor and very responsive. I would take again.

After two failed attempts at my university, this course helped me understand Calculus. The live maths tool along with Dr. Curtis were especially helpful, allowing me to visualize concepts and expand my understanding. The explanations were clear, the examples practical, and I could learn at my own pace, which built my confidence. Thank you.
