So in particular the basis Direct link to Srgio Rodrigues's post @Jonh I believe you right, Posted 10 years ago. You stick u there, you take Then \(w = -w'\) is in both \(W\) and \(W^\perp\text{,}\) which implies \(w\) is perpendicular to itself. ( Since the \(v_i\) are contained in \(W\text{,}\) we really only have to show that if \(x\cdot v_1 = x\cdot v_2 = \cdots = x\cdot v_m = 0\text{,}\) then \(x\) is perpendicular to every vector \(v\) in \(W\). a null space of a transpose matrix, is equal to, of the orthogonal complement of the row space. then we know. If you are handed a span, you can apply the proposition once you have rewritten your span as a column space. ( Thanks for the feedback.
