Workload

Content in MATH 1554 is typically assessed through homework, quizzes, and exams. These tend to have a mix of questions on theory, often given as true/false questions, and computation. While the course requires no formal proofs, the theoretical nature of MATH 1554 can be challenging for first-year students. Homework may not be very time-consuming, but questions often involve a bit of thinking.

Prerequisite Knowledge

Almost no prerequisite knowledge is required, apart from algebra and trigonometry.

Equivalent Courses

• MATH 1553 is the introduction equivalent, which does not cover as many topics as MATH 1554.
• MATH 1564 is the honors equivalent, which uses proofs and is more theoretical than MATH 1554.

Future Outlook

MATH 1554 is generally taken by freshmen due to it having almost no prerequisites. However, future calculus classes, such as MATH 2550, MATH 2551, and MATH 2552 will use linear algebra concepts such as matrices, determinants, and eigenvalues. In addition, linear algebra is important for computer science majors, who have to take classes that require linear algebra, such as MATH 3012 and CS 3510.
