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.

Pros: once you get going, you can go really fast. The visual textbook is pretty cool. The instructors were very responsive.
Cons: the movies are great, but the software crashes more than it should. Sometimes it is just a hassle doing things in the software instead of on paper, but once I got used to the software, it was ok.

Excellent course that you can take at your own pace. The instructor is excellent and I was able to get my questions answered quickly and complete this for an EMBA prerequisite. I would recommend this course to anyone trying to learn basics of calculus on their own timeline. The class prepared me well for my coursework at MIT.

A great way to learn probability theory through visualizations, code, and math. Rather than just solving equations through pencil and paper, this course helped me to see how how probability distributions form and behavior through simulations and visuals. I would recommend this course to anyone looking for a way a more interactive way to learn mathematics and at their own pace.

After completing all the math offered by my highschool, I switched over to Roger Williams for Calculus II and onward. Overall, it has been a pretty great way to understand the topics online, with transferrable college credits. The exams are not terrible, and the courses cover the vast majority (if not all) of topics covered by traditional courses, with some unique ones added to. So far, I have taken four courses, with another one or two before I graduate.

The only problem with the course is the lack of pen and paper work. This shouldn't come as a crazy surprise with an online course, but there is not much emphasis on symbolic computation. Mathematica or other software does most of the heavy computation for you. The lectures usually show how to solve the problems through paper, but those skills are rarely put into practice. Literacy Sheets act as a way to do some of that (especially with the Calculus II & III course).

All in all, this isn't a huge issue. I just memorize and practice things like double integration, Laplace, ODE solving, matrix diagonalized form, row operations, etc. With a little outside work, this resolves itself. Without Roger WIlliams, I probably would not have been able to take any of these math courses in highschool.

So overall, a great choice for highschool advanced math, especially with transferrable credits.

The professor as well as the TAs give great feedback when you need help with problems and the videos are great at explaining concepts. Return time on work is good and the work is not too much to handle.

Courses Completed: Linear Algebra
This course gives a perspective on Linear algebra that no traditional course does. I’d say i gained much more intuition for this subject from the DC course than my friends who took traditional courses elsewhere. As a cs major, this version of learning with visualization has helped me a lot in understand ML models. However the course doesn’t have videos for the last 2 chapers so i had to self learn with the mathematica notebooks. Response times are a little slow but since it’s a remote class, i guess it’s justified. Overall amazing course and definitely take this over traditional lin alg classes.
