YAMT: Finding a basis for 8 vectors..

[Syringer]

I have 8 vectors of 5 elements each that generate W. I have to find a subset of the 8 vectors that is a basis for W. How do I do it??

Are you just trying to sound smart or do you honestly need help?

5 elements is 5-D space. Keep picking from them till you get 5 linearly independent ones that define the subspace.

Look here for more info: http://mathworld.wolfram.com/VectorBasis.html

This was about 4yrs ago for me so I dont remember the exact details

Have you ever taken a course in linear algebra? This is a perfectly normal question...

MY GOD LINEAR ALGEBRA SUCKS.

I still ask myself WHY I took it when it wasen't a reqired course. (as if 5 quarters of calc and 1 of diff eq wasen't enough).
