A set is linearly independent if and only if the set of coordinate vectors with respect to any basis is linearly independent.

Created almost 9 years ago, updated about 8 hours ago

The coordinate map relative to a basis is a linear isomorphism, so it preserves and reflects linear relations. Explicitly, $\sum_ic_iv_i=0$ iff $\sum_ic_i[v_i]_B=0$. Therefore a list is independent iff its coordinate-vector list is independent.
