Prerequisite Knowledge

Single Variable Calculus

Single variable calculus, covered in MATH 1551, 1552, and AP Calculus, is an important prerequisite for MATH 2551. Multivariable calculus applies single variable calculus concepts such as limits, derivatives, and integrals to functions with more than one input and/or output. Multivariable calculus should not be seen as the next course in a linear sequence of calculus courses; rather, it should be seen as an outward expansion of all single variable calculus topics. For example, while no new integration techniques are introduced in multivariable calculus, with the exception of the Jacobian, the concept of integration is applied to 2D and 3D regions in multiple coordinate systems.

Linear Algebra

While linear algebra, covered in MATH 1553, 1554, and 1564, is listed as a prerequisite for MATH 2551, topics that require prerequisite knowledge of linear algebra are rarely seen in MATH 2551, with the exception of the matrix determinant. However, linear algebra may provide a theoretical background for concepts such as vectors and determinants.

Relation to the Overall Curriculum

MATH 2551 is generally taken sometime between late freshmen year and early sophomore year due to having a couple prerequisites. Furthermore, MATH 2551 itself is an important requirement and prerequisite for all engineering majors, with the exception of computer engineering.

Workload

Content in MATH 2551 is typically assessed through homework, quizzes, and exams. Homework tends to very time-consuming and focuses heavily on computation. Quizzes and exams also focus more on computation but do contain a couple theoretical questions, often presented in a true/false format. Exam problems are usually shorter than homework problems due to time constraints.

Registration

MATH 2551 is a linked course, as it has a studio. You must register for a lecture section (marked with a single letter A, B, C, etc.), and its corresponding studio section (e.g. if you are in Section C, you must register for studio sections that start with C, like C01, C04, etc.). You must register for both of these at the same time.

And while it isn't a prerequisite, you will use some Multivariable Calculus concepts (such as vector valued functions and Green's theorem) in PHYS 2212.

Prerequisites

All of the Following:

• D or higher in MATH 1552 or a 4+ on AP Calculus BC.
• D or higher in MATH 1553, MATH 1554, or MATH 1564.

Equivalent Courses

MATH 2561 is an honors version, and goes over the topics in MATH 2551 at a much higher level (along with a few extra topics).
