I studied Linear Algebra about two years ago, and I have seen on a lot of math sites that the prerequisites for this course are Arithmetic and Algebra;
However, when I studied Linear Algebra I would often run into rotation matrices, where you had to work with trigonometric functions, so shouldn't this mean that this course expects you to have studied Trigonometry as well?

The way I see it, it seems like the ideal course order up to Linear Algebra should be Arithmetic/Algebra/Geometry/Trigonometry.

I guess it's already fairly advanced ^^. I did a little bit of math with vector spaces (Stats/Econometry) but never met these objects , damn Maths are fascinating . I was a real labrador when it started to be advanced and I just like to use them as a tool now. I saw the ultra basics like transposition, inverse, tensor product blahblah. It's far away now .
As for trigonometric functions, you mean an advanced comprehension of them or the basics? In french highschools for "scientific" specialization, before going to University, or Schools in general, you approach these functions in classical trigonometry (not very good memories lol) for example with the polar coordinate system (also with complex numbers), but that's basic, at least you see them once.

When I started college I had to take a math placement test. My scores indicated proficiency in Trigonometry, otherwise it was the first course required for a math major/minor (well, unless you had to take a remedial course). So, for me, Trigonometry was assumed to be a basic foundation course for my degree.

Linear Algebra typically requires knowledge of Calculus & Differential Equations as far as I know, which implies you should have already learned Trigonometry in Pre-Calculus courses.

I couldn't remember a specific Trigonometry course that I had to take in college...way back when.

I perused the current course catalog - trigonometry, including trig functions, is put into the pre-Calculus course and all of the Calculus courses and completing the Calculus courses is a prerequisite for Linear Algebra.
