Calculus 3 - Vector 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
Calculus 3 - Vector Calculus - 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.

Calculus 3 Course Preview



Calculus 3 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 3
  • Calculus 4
  • Calculus III
  • Calculus IV
  • Vector Calculus
  • Calculus of Many Variables
  • Calculus of Several Variables
At Distance Calculus, we call our "Calculus 3" course as Multivariable Calculus - DMAT 355 - 4 credits.

Calculus I from Distance Calculus was wonderful! I took AB Calculus in high school, but I didn't take the AP Calc exam. Instead I took Calculus I with Distance Calculus, and it was so much better! It was a little review of topics, but not really. I really understood calculus when I finished!

I've taken Multivariable Calculus, Linear Algebra, Differential Equations, and Probability Theory through Distance Calculus. All four courses were awesome. Dr. Curtis and the TA's were very responsive and helpful.
The biggest advantage of these courses, compared to taking a traditional course, is that in addition to the theory, I was forced to also think computationally. I have become quite adept at using LiveMath and Mathematica for doing calculations and plots.

Awesome classes! I was really weak with Calculus, so I retook Calc 1 and kept going into Calc 2. I feel like I finally understood Calculus. The finals were pretty thorough, but not nearly as stressful as the blue book exams. I highly recommend these courses!

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.

Great course. Professor Curtis and the TAs graded quickly and gave really helpful feedback that made the class feel smooth and manageable. Definitely recommend it.
