Like in my college, courses often are written in a list like this


Name = Credits = Vector

Math = 3 = [0-3-1]

How do you read it?

I certainly thought I did until I read this...

Isn't that just course weight?

Usually, [3-1-0] could mean that you're expected to attend 3 lecture hours, study for about 1 hour, and you have 0 hours of labs. It was like that at my former college.

Like in my college,

Then you should ask somebody at your college what it means. I suspect it probably means something like "3 hours lecture, 1 hour lab, 0 hours recitation." Or maybe "3 hours lecture, 1 hour recitation, 0 hours lab." Or maybe "3 hours lab, 1 hour lecture, 0 hours recitation." Or maybe...

I don't know who to ask, I am away from my college's city right now.

Each lecture runs an hour and a half long but we have it three times a week. No such thing as recitation in our college, there aer labs which does run 1 hr

Well... not us. Whatever that is, it's probably something specific to your college.

Also it really irks me that it's called a "vector."

But it is a 1-d array of numbers!

...and the norm represents how much time you spent on the class!

In C++, a vector is just a 1D array of any object

I guess that usage is grandfathered into my psyche :tongue:

Can't you shoot a professor an email and ask?

Any professor???

Well, maybe then you could ask as you're being dragged away to jail.

I'll take a stab at it...

I'm guessing that you're referring to a course catalog published by your university? I'm also going to assume that you're not using the standard, mathematical definition for the '=' sign because I can't see any reasonable equivalence between the names, numbers, and symbols in your post.

Since the word "vector" can, essentially, mean a course or direction, is there a legend on the catalog that would explain why the '1' has been assigned to the math course to which you're referring? Perhaps there are different "directions/paths" one can follow that would correspond to specific courses? (Pure, Applied, Discrete, etc.)

For example, math courses that are typically taken when pursuing a degree in pure/general mathematics might be assigned a "vector" value of '1'. Then, when the student is looking through the catalog, they can easily identify electives/prerequisites that would be congruent with their educational goals.

That's the only interpretation I can come up with at the moment.
