The prerequisite to this course is 18.01 Single Variable Calculus.
This course covers vector and multi-variable calculus. At MIT it is labeled 18.02 and is the second semester in the MIT freshman calculus sequence. Topics include vectors and matrices, parametric curves, partial derivatives, double and triple integrals, and vector calculus in 2- and 3-space.
As its name suggests, multivariable calculus is the extension of calculus to more than one variable. That is, in single variable calculus you study functions of a single independent variable
In multivariable calculus we study functions of two or more independent variables, e.g.,
z=f(x, y) or w=f(x, y, z).
These functions are interesting in their own right, but they are also essential for describing the physical world.
Many things depend on more than one independent variable. Here are just a few:
Single variable calculus is a highly geometric subject and multivariable calculus is the same, maybe even more so. In your calculus class you studied the graphs of functions y=f(x) and learned to relate derivatives and integrals to these graphs. In this course we will also study graphs and relate them to derivatives and integrals. One key difference is that more variables means more geometric dimensions. This makes visualization of graphs both harder and more rewarding and useful.
By the end of the course you will know how to differentiate and integrate functions of several variables. In single variable calculus the Fundamental Theorem of Calculus relates derivatives to integrals. We will see something similar in multivariable calculus and the capstone to the course will be the three theorems (Green's, Stokes' and Gauss') that do this.
After completing this course, students should have developed a clear understanding of the fundamental concepts of multivariable calculus and a range of skills allowing them to work effectively with the concepts.
The basic concepts are:
The skills include:
This course, designed for independent study, has been organized to follow the sequence of topics covered in an MIT course on Multivariable Calculus. The content is organized into four major units:
Each unit has been further divided into parts (A, B, C, etc.), with each part containing a sequence of sessions. Because each session builds on knowledge from previous sessions, it is important to progress through the sessions in order. Each session covers an amount you might expect to complete in one sitting.
Within each unit you will be presented with sets of problems at strategic points, so you can test your understanding of the material. At the end of each unit, there is a comprehensive exam that covers all of the topics you learned in the unit.
MIT expects its students to spend about 150 hours on this course. More than half of that time is spent preparing for class and doing assignments. It’s difficult to estimate how long it will take you to complete the course, but you can probably expect to spend an hour or more working through each individual session.
Most sessions include video clips from lectures of Professor Denis Auroux teaching 18.02 recorded live on the MIT campus in the fall of 2007. The video was carefully segmented by the developers of this OCW Scholar course to take you step-by-step through the content. The lecture video clips are accompanied by reproductions of the materials presented on chalkboards used during the class.
This OCW Scholar course includes dozens of Recitation Videos – brief problem solving sessions taught by an experienced MIT Recitation Instructor – developed and recorded especially for you, the independent learner. Meet the recitation instructors and learn more about how to benefit from this help by watching their introductory video.
The readings in each session are adapted from materials that have been used for years to teach multivariable calculus at MIT. They provide a slightly different perspective on the material as well as a written record of the topics covered in lecture.
"Examples" present problems with their solutions. Take a minute to think about how you would solve each problem before you read the solution. Reading these solutions carefully will prepare you to solve similar problems on your own.
In some sessions you will have the opportunity to work with a Mathlet. These interactive learning tools will help you visualize multi-dimensional objects and observe their changes as you manipulate different variables.
"Problems and Solutions" let you test your mastery of the content of each session. Solve the problems on your own and check your work against the solutions before proceeding to the next session.
At the end of each Part is a Problem Set. As you start each part familiarize yourself with the problems in its problem set; this will enable you to work on each problem as you gain the knowledge you need to solve it. Once you have completed the problem set you can check your answers against the solutions provided. (The problem sets are carefully selected from a longer list of questions available to you. Do not hesitate to work any problem that piques your interest.)
Each unit ends in an exam. To prepare for an exam first work through the sample exam then check that you are proficient in each of the topics discussed in the exam review lecture. You should also review the solutions to any problems you found difficult in that unit. Allow yourself one hour to work each exam and three hours to complete the final. The exams are quite challenging; do not be surprised if you are unable to answer all of the questions correctly in the time allowed.
This OCW Scholar course is self-contained and no textbook is required. If you have access to a multivariable calculus text it will probably serve as a useful companion to this course, although you might have to deal with slight differences in terminology and notation.
MIT OpenCourseWare has teamed up with OpenStudy so you can quickly and easily connect with others working on this course. Through this site, you can find other students interested in 18.02SC Multivariable Calculus: work together on assignments, ask each other questions about the exams, or just discuss the topics of the course.
