About this course

Skip About this course

Variables are all around us: temperature, altitude, location, profit, color, and countless others. Multivariable Calculus is the tool of choice to shed light on complex relationships between 2, 3, or hundreds of variables simultaneously. Some of the multivariable questions considered in this course include:

  • How can one quantify the efficiency of a power plant?
  • How much snow can a roof safely hold?
  • Over the next 100 years, how high will continually melting icebergs raise sea levels?

The key tool for answering each of these questions is multivariable integration.

In this course, you will learn how to set up, solve, and interpret many types of multivariable integrals:

  • double integrals of scalar functions in any coordinate system,
  • line integrals of scalar and vector-valued functions,
  • triple integrals in cartesian, cylindrical, and spherical coordinates.

Physical applications will be highlighted, including the use of integrals to compute the work done by a force field, or the flux caused by a velocity field.

Finally, you will learn powerful tools for simplifying integral computations, including the Fundamental Theorem of Line Integrals and Green’s Theorem.

Frequently Asked Questions

Skip Frequently Asked Questions

Is 18.02.1x required for this course?

Yes. Although any first course on multivariable calculus will also work! The key here is that you must be comfortable with scalar and vector-valued functions of more than one variable, how to interpret them geometrically, and how to take derivatives of them.

Can I take this course concurrently with 18.01.2x?

We do not recommend this! We will expect that you are already familiar with many of the integration techniques introduced in the last unit of 18.01.2x at the beginning of this course.

Who can take this course?

Unfortunately, learners residing in one or more of the following countries or regions will not be able to register for this course: Iran, Cuba and the Crimea region of Ukraine. While edX has sought licenses from the U.S. Office of Foreign Assets Control (OFAC) to offer our courses to learners in these countries and regions, the licenses we have received are not broad enough to allow us to offer this course in all locations. edX truly regrets that U.S. sanctions prevent us from offering all of our courses to everyone, no matter where they live.
