General information

Course description

This linear algebra course is the third semester of our Math 1110-1120-2210-2220 calculus sequence, which is recommended for most students who plan to major in mathematics or certain related fields. See First steps in mathematics for advice on which calculus sequence and linear algebra course to choose.

At its root, linear algebra is the study of systems of linear equations. Systems of linear equations are ubiquitous in the natural and social sciences. One major contribution to the topic was made by Gauss (1777–1855), who was confronted with large systems of linear equations in his work on astronomy and developed the famous method of least squares to cope with measurement errors. Later in the nineteenth century Cauchy, Sylvester, Cayley and others developed the concept of a matrix, which provides the most convenient language for the theory and practice of linear equations. Matrices are intricate algebraic objects with many fascinating properties, but they also provide a bridge between linear equations and vectors, so infusing the subject of linear algebra with a strong geometric flavor. We will delve into all these topics, as well as the notions of determinant and eigenvalues, which are important numbers associated with any square matrix.


Two semesters of calculus with high performance or permission of department.

Homework and quizzes

There will be regular homework and quizzes.  Homework assignments with due dates will appear in the homework link above and, except for the first assignment,  will  due in discussion section.    


There will be two evening prelims and a final exam. The schedule is on the Exams page.

No books or calculators or notes will be allowed on the exams.

We must have one week's advance notice of exam conflicts.

If you require special accommodation on prelims and exams, such as extended time or quiet time, you must obtain a Faculty Notification Letter from Student Disability Services and contact your recitation instructor two weeks before the prelim or exam to make the necessary arrangements.

The dates of the evening prelims may include Religious Holidays for some students. NYS Education Law 224-A mandates that faculty make available an opportunity to make up any examination missed because of religious beliefs. In order to facilitate preparation of makeup exams, students intending to be absent in order to observe any of these holidays are requested to notify the instructor by 9/5/2014.


In addition to office hours, you can get free one-on-one tutoring at the Math Support Center.

Math 1021 is a one-credit course which offers support for math 2210.  Here is more detailed information.


Grades will be determined using the following weights:  Final exam - 30%, Prelim 1 - 25%, Prelim 2 - 25%, Section grade - 20%

Academic integrity

You are encouraged to discuss homework problems with your classmates. Copying other people's solutions is not allowed however and will be penalized by the grader.  

You are expected to abide by the CU Code of Academic Integrity.
