find the orthogonal complement of the subspace of R^3 spanned by (1, 2, 1)^T and (1, -1, 2)^T ================================================================= 我這樣寫 [a] [1] [a] [ 1] <[b],[2]> = 0 <[b],[-1]> = 0 [c],[1] [c] [ 2] 解聯立 c = 3b [ a] [1] [0] span{[ b]} => span{[0], [1]} [3b] [0] [3] 解答是(-5, 1, 3)^T 請問我是什麼地方錯了? 謝謝!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.228.28.13

c=3b 然後代回a+2b+c=0 => a=-5b
