Really?
I took a semester of linear algebra, too, and it was hands down, full stop the most useless course I took in my entire college career. Like the most useful seeming thing was solutions of groups of linear equations, but I have never been in a situation where I knew or could construct an equation to build into a system. We touched somewhat on linear regressions, but never got far enough into them to do anything useful. Other than that it was a huge amount of fairly basic algebraic geometry.
I'd already completed two semesters of calculus, statistics, relational algebra and a class in formal logic. There was no translation in the program from mathematics to applications in computer science, either, so everything was left so abstract and disconnected from any purpose in reality that it was merely learning the mechanics of solving complex problems without ever beginning to understand how to identify such a problem or what the solution actually meant. Nobody comes up to you and says "here is a matrix that represents a set of linear equations. solve it." and that's all that class did. Where do these equations come from? How do I construct them? How do I know they're related? What does performing these mathematical operations mean? Why is this mathematical solution important? Knowing how to multiply 6 * 7 is fantastic, but if we're talking about 6 as the fourth octet of an IP address, and 7 as the number of chairs in the conference room that are blue, then multiplying 6 * 7 isn't particularly meaningful. It was like taking calculus without physics, or trying to learn SQL without a database to play with, or learn how to write a class without a useful object to represent and useful functions to operate against. It was a complete waste of time.
