Finals

Linear Algebra final on the weekend.

Aside from browsing /sci/, what's the best way to remember all these theorems?

Have them tattooed on your torso in reverse so you can stare at them while you brush your teeth and shave. Assuming you do either.

You don't remember 'em, silly. Nobody does.

OP, good luck.

Just do lots of exercises -- it's the only way.

Agreed. I did like 300 sit-ups the night before my linear algebra final, and I aced it.

All else phails, remember the minimum set of assumptions/definitions, and derive the rest.  That's still quite a challenge though :(.

Best of luck to you.  Are you using the textbook by Axler?

I put all the theorems into an excel spreadsheet which has a column pointing to questions in the book that used them and an extra notes thread for theorems that are more of an algorithm and show a runthrough on how to use them.  That way when I wanted to study for them, I'd just print it out and look it over.  It helped me a lot, but this is more something you start doing and reap later.

If you think that's a little much, you should have seen the guy I sat next to.  He wrote his class notes in XML on the fly.  He claimed he had some sort of interpreter that allowed him to catagorize and collapse/expand relavent topics.  A little overkill if you ask me.

wtf? it's a piece of cake. linear algebra is the easiest maths course ever.

Hope that helps. <3

wow that was easy...

proofs were:

- If T(v1) , ... , T(vp) is a linearly indpenedent set, show that v1, ... , vp is also linearly independent.

- If matrices A and B are similar, show that they have the same characteristic polynomial

- If W-perp is the orthogonal compliment to W, a subset of Rn, show that W-perp is also a subset of Rn.

All other stuff was computations.

1/2 of the ppl will get like 60% too...

wow, they suck

See, nothing to it.
