SUMMARY

The discussion centers on proving that a subspace of a finite-dimensional vector space is also finite-dimensional. The key equation referenced is dim(V) = #basis vectors, which establishes the relationship between the dimension of a vector space and its basis. The initial attempt involved summing the basis vectors of the vector space and subtracting those of the subspace, but this approach was deemed flawed as it presupposed the finiteness of the subspace's basis vectors. The core question raised is whether a finite-dimensional space can contain infinitely many linearly independent vectors, which directly relates to the proof in question.

Homework Statement

Prove that the subspace of a finite dimensional vector space is finite dimensional

Homework Equations

dim(V)=#basis vectors

The Attempt at a Solution


I was thinking about making a summation of the basis vectors in the vector space and the subtracting the summation of the basis vectors in the subspace. That way I get a finite# of basis vectors left over. But that thinking turned out to be flawed because I'm assuming that the #of basis vectors in the subspace is finite(what I'm trying to prove). So I'm back to square 1.
