Calculus 2 vs Multivariable Calculus - Distance Calculus

Calculus 2 (Calculus II) and Multvariable Calculus are two completely different courses.

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.

This was a great course. Flexible and informative with a great professor. It's a great option if you need to fill a prerequisite fast or if you enjoy working at your own pace.

POSITIVES:
One of the best math classes I have ever taken. The lessons made the failures of my previous professors very apparent. In a few short minutes, things that I used to struggle with just clicked. This professor is top notch and really wants you to understand how to use the material.
NEGATIVES:
The SOFTWARE is extremely frustrating. Even after taking the time to learn, there are countless glitches. You learn to work around them, and overall, the software makes the math convenient, but its failures are sorely felt throughout the course. Make sure you save often as it crashes regularly, especially with graphs.
The assignments are easy enough but some of them don't line up with the taught material. Be prepared to do some of your own independent research to get a deeper understanding of why things are the way they are.

Is the course perfect? No. However, it was by far the best option available. I have learned quite a few things not normally taught in a Calculus course. However, the course lacks a lot of paper solving and integrating, which is to be expected in an online course.

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.
