Multivariable Calculus (Calculus 3) in High School

Many very motivated and eager high school students will finish Calculus AB (Calculus I) and Calculus BC (Calculus II) during their junior or senior year of high school.

If you finish these AP Calculus courses during your senior year, then one option to get ahead with your academic plan is to complete the next course - Calculus 3 (Calculus III) - Multivariable Calculus - during the summer before you start your new undergraduate university - or take Multivariable Calculus during your senior year. Earning real collegiate academic credits for Multivariable Calculus and then transferring those credits to your new undergraduate college/university is an excellent way to start your new school with some advanced mathematics credits under your belt.

Some very eager students may finish Calculus I (AB) and Calculus II (BC) during their junior year of high school. For these students, enrolling in multivariable calculus, honors multivariable calculus, honors vector analysis, honors calculus 4, honors calculus IV, and perhaps Differential Equations and Linear Algebra, via Distance Calculus @ Roger Williams University is an excellent way to FINISH your lower division mathematics courses even before you step foot onto your new college/university campus the following Fall semester!

Here is a video about our Multivariable Calculus course via Distance Calculus @ Roger Williams University:

Multivariable Calculus & High School

After AP Calculus for High School Students

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 did not enjoy Calculus I at my school. I retook Calculus I, and then Calculus II, over the summer via Distance Calculus and it was awesome. I started my sophomore year back on track and ready for my physics classes. I struggled with the MathLive software but I guess it was alright.

I needed to finish the Business Calculus course very very very fast before my MBA degree at Wharton started. With the AWESOME help of Diane, I finished the course in about 3 weeks, allowing me to start Wharton on time. Thanks Diane!

Dr. Curtis's lessons were well taught, and livemath wasn't too bad once you understood it. Some of the assignments were pretty difficult and required some more explanation, which was hard to get outside of the given lessons.

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.

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.

Im a visual learner and had a difficult time understanding multivariable calculus my first go around, and found this course offered by Roger Williams University, which uses real-time 3d graphing of the equations. I would see my work be manipulating the models, which gave a robust understanding of what each variable did. absolutely loved the course and class recordings.
