MA283 Week 12

Welcome to Week 12, the last week of our semester.

In Lecture 22, we will discuss the orthogonal projection of a vector onto a subspace of an inner product space, and the application of this concept to the problem of finding an approximate solution to an overdetermined system of linear equations. A system is overdetermined if is is inconsistent due to having more equations than variables.

Here is Lecture 22.

Slides for Lecture 22.

In Lecture 23, we will talk about the end of semester exam. Please see the Blackboard page for some advice on the exam, and sample exam-type questions.
