comment Only 'atomic' vectors as part of the base of a vector space?
Is that how it's done? Finding n vectors where n is the dimension of the given vector space - 1 that, multiplied with different scalar result in the original vector describing the vector subspace?

Yeah following Tomas's comment I already figured that out, but thanks for putting it in an answer.

comment Define parameter in linear system to get different number of solutions
Thanks so far sds! I'm not quite sure how to execute this tho, do I compute the determinante of the unaugmented coefficient matrix? $A_0$ puzzles me a bit

Maybe it's me, but I don't see how you reduced that further. Mind telling me? ;)

sorry, but the $^T$ puzzles me a bit. Besides that, good answer, will try it asap

comment Computing cross product using norm and angle
made a mistake in my original question, 1. transforms into $||-7(v\times w)||$

comment Cross product as factor in dot product
thanks so far, I didn't know I could handle cross products like that. I've transformed this into $5v(w \times v)-15w(w \times v)$ although this looks a bit tidier, how can I compute that? Is there a relation between norm and cross product I'm missing here?

I just didn't know the difference, my choice of words wasn't based on any literature

isn't cos(2pi / 3) something like 0.99something?
