    • What is Multivariable Calculus?

    • How to Approach Problems in Multi

    • 3D Coordinate Systems

    • Vectors

    • Dot and Cross Product

  • Double Integrals1:01:40
    • Rectangular and Non-Rectangular Area of Integration

    • Polar Coordinates

    • Applications of Double Integrals

  • Triple Integrals1:11:14
    • Rectangular Coordinates

    • Cylindrical Coordinates

    • Spherical Coordinates

  • Domain and Range of Multivariable Functions (Extra Lecture)19:57

    There aren't many instances in multivariable calculus where not knowing domain and range will hinder you (unless it's specifically a question about domain and range), so I figured I would put it in the form of a mini-lecture with a couple examples.

  • Applications of Integrals (Extra Lecture)9:31

    Some examples on how you would use integrals in real life

Requirements

  • Single Variable Calculus (Calc 2 is NOT required)
  • Basic geometry (including trigonometry)
  • Basic 3D visualization skills

Description

Multivariable calculus is often seen is an entirely new kind of calculus, but in reality, it's an application of single variable calculus to 3-dimensional space. Topics covered include vectors and surfaces, partial derivatives, double and triple integrals in various coordinate systems, and applications of both derivatives and integrals in 3D. This course covers all of the essential topics to multivariable calculus, but not advanced topics that some undergraduate courses don't cover such as Green's Theorem, Stoke's Theorem, Divergence Theorem, surface integrals, or vector integrals. This course will get you exactly what you need for your freshman or sophomore level multivariable course, and will be a great review for an upper level vector calculus course!

I find too often that students don’t know why they are learning something or how it relates to future classes or career. Some professors are too focused on getting the material over to you and giving you the test. Sound familiar? I will teach you how to think like an engineer, which means being able to break down complicated problems into simple pieces that you already know how to do! I recognize that students value simplicity and logic over complicated derivations and memorized processes. I will teach you the simplest way that has helped my students become successful for the past 5 years.

By the end of the course, you will know how to approach fundamental problems in each of the major topics and explain why they are relevant in engineering. The course is designed to also be used as a reference when you are taking the full version of the course as well, so don’t be afraid if you don’t pick everything up the first time you see it! My hope is that you have the “ah-ha that’s why Scott approached it that way” moment when you take the real course.

Who this course is for:

  • Sophomores in math-based college majors
  • Students who will be taking Multivariable Calculus in the future
  • Students who are currently enrolled in Multivariable Calculus
  • Young professionals who want to brush up on their math skills
  • Students who want to review Multivariable Calculus in preparation for Vector Calculus (Calc 4)
