hey guys,
i've finally decided to enroll in school again
to study the math that i'm sorely lacking.
i know that ultimately i want to take a course
in linear algebra, and that Grassmann algebra in
particular is something i want to be familiar with.
the college catalog lists trigonometry and calculus
as prerequisites for linear algebra, so this is going
to be a long haul if i can stick with it. i nearly
bombed out of algebra II in high school, and never
studied math again after that ... except the bits
and pieces i picked up as a tuning theorist.
i feel like i'm missing out on too much new discovery
here on tuning-math, and want to get up to speed.
i haven't selected any particular classes yet.
i will certainly have to start with regular algebra
all over again, and will probably only be able to take
one course per semester. advice is appreciated.

Congratulations, monz!! Best of luck.

Do it, Monz. Now that you have the motivation, you'll do much better
than you did in high school. In fact, I have a feeling you'll ace
these classes . . .

I have a friend who got a degree in Business Admininstration and
then wanted to take some computer science classes for fun. They
burried him with a list of math prerequsites which I think he
worked hard on for maybe a year and a half and then burned out
without ever taking the computer classes he wanted.
Trigonometry and calculus are really irrelevant to linear algebra,
and Grassmann algebra is (i think) abstract algebra (groups, rings,
homomorphisms, etc) applied to linear algebra. In other words,
it is *much* harder, as in you get a bachelors degree in math and
then you take it in graduate school. Of course, you wouldn't need
the full force of it to follow most of the tuning-math discussions.
So maybe what you want is to get up to speed on basic algebra,
and then just go to the linear algebra class?

Trig and calculus are both handy to know, and do come up in tuning-math theory. So if they're pre-requisites, why not give them a try? It depends on how advanced the courses get. Easy trig and calculus are all you need.
Grassman algebra is based on wedge products. It's not that difficult. But it isn't that well known, so they'll only expect hard core mathematicians to learn it. Get basic algebra, and you should be able to learn it from the online materials, and questions here.
Also, you can avoid a lot of linear algebra if you know Grassman algebra. So choose your poison ...

It's a subject normally taught to grad students which should be taught
to sophmores. In a linear algebra class, the sophmores will need to
learn the determinant. Textbook authors usually approach this from the
point of view of computing them by hand using Gaussian reduction,
which is pointless and does not advance your understanding much. They
should teach it from wedge products.
