Vector 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. 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 advanced 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:

Calculus 3 Course Info

Multivariable Calculus & High School

After AP Calculus for High School Students

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.

I have difficulty learning calculus based math, akin to dyslexia when examining the symbolic forms, equations, definitions, and problems. Mathematica based calculus courses allowed me to continue with my studies because of the option of seeing the math expressed as a programming language for which I have no difficulty in interpreting visually and the immediate feedback of graphical representations of functions, equations, or data makes a huge impact on understanding. Mathematica based calculus courses should be the default method of teaching Calculus everywhere.

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!

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.
