Differential Equations Course - Distance Calculus Course Information

Differential Equations course can best be described as a "first course in the study of differential equations of a single independent variable".

This course has many names, all being equivalent:
  • Ordinary Differential Equations
  • Introductory Differential Equations
  • Differential Equations of a Single Variable
  • DiffyQ !


Our Differential Equations course differs from a classroom/textbook-based course in that we employ Mastery Learning so that you complete all assignments at 100% to assure competancy, as well as our curriculum shifting the course to a laboratory-style course, where theorem/lemma/proof type exposition is replaced by running experiments in Mathematica as you would in a science laboratory to empirically deduce the concepts and behaviors of differential equations, both solvable (classically) via hand-based techiques, as well as studying differential equations that can only be solved and investigated graphically and numerically using a computer.


At Distance Calculus, we call our "Differential Equations" course as Differential Equations - DMAT 321 - 3 credits.

I took Calculus II through Distance Calculus and can't recommend it enough. Being able to take the course at my own pace while I was working full time was tremendously helpful, especially since I hadn't taken a math course for 5 years prior. The instruction was excellent and the software they used to teach the course was intuitive and facilitated the learning process very well. This calc II class enabled me to take multivariable calc, linear algebra, and real analysis at Harvard University's extension school, which ultimately qualified me for the economics PhD program that I will graduate from next year. 8 years on, I'm still grateful to Professor Curtis and Distance Calculus.

This course provided an excellent chance to learn about Calculus...again. I took calculus in high school, but I learned so much more with this course!
It does take a good amount of time to do all the lessons, so definitely keep on top of them, but all the exercises helped me to really understand the material. And the nice thing is you can do it on your own time at home.

Courses Completed: Multivariable Calculus, Differential Equations, Linear Algebra
After a really rough first year of calculus, I completed all of the second year calculus courses with Distance Calculus. It was like night and day the difference. My first year was so boring and monotonous. Multivariable Calculus, Differential Equations, and Linear Algebra through Distance Calculus were just so much different - so not boring at all. I thoroughly enjoyed these courses. So engaging.

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.
