    Linear Algebra: intersection of subspaces

    Homework Statement I'm working on a problem that involves looking at the dimension of the intersection of two subspaces of a vector space. Homework Equations M \subset V N \subset V dim(M \cap N) [\vec{v}]_{B_M} is the coordinate representation of a vector v with respect to the...
