Multivariable Calculus Online Course For Credit

If you have finished your Calculus I and II courses, then the next set of courses to complete are:
  • Multivariable Calculus
    Also called Vector Calculus, Calculus III, or Calculus IV - they are all essentially the same course
  • Differential Equations
  • Linear Algebra
  • Probability Theory
Multivariable Calculus is an excellent course to jump off into the online course experience - the curriculum is highly visual, and the course content is less about "drill & practice" type mathematics, and more about concepts and relationships, generalizing the theorems of 1-dimensional calculus to multiple dimensions.

No matter which major or specialization you might be aiming for - computer science, engineering, physics, economics, business, data science - a strong background in multivariable calculus will put you ahead of the pack and give you the foundations necessary to excel in these other academic and practical disciplines.

Multivariable Calculus course can best be described as a "the first semester course of Differential and Integral Calculus to functions of many variables".

This course has many names, all being equivalent:
  • Calculus III
  • Calculus IV
  • Vector Calculus
  • Calculus of Many Variables
  • Calculus of Several Variables
At Distance Calculus, we call our "Multivariable Calculus" course as Multivariable Calculus - DMAT 355 - 4 credits.

I highly recommend this course. I started the Kennedy School at Harvard with a last-minute admission, but my application required the Liberal Arts calculus course, so I had to finish the course in 3 weeks. Diane was an awesome instructor! The class was surprisingly interesting. If you need to take calculus fast, this is the program to use.

Nothing but praise for Dr. Curtis. He's an excellent professor who is very responsive and knowledgeable. I did this course at night while working full-time, and I often skyped him late in the evening with questions. He never took long to respond, regardless of when it was. I finished this course in about a month and a half, and I worked for it. For those looking for an easy A, this is not it. You will have to put in serious work, but you will come out of the course with a good understanding of the material, especially if you apply yourself throughout the entirety of the course.

I took Multivariable and Diff Eq during the summer. The DiffEq course was awesome - very useful for my physics and engineering course. I was unsure about Mathematica at first, but I got the hang of it quickly. Thank you Distance Calculus!

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.
