[题目]把向量组 (alpha )_(1)=(1,0,-1,1) , (alpha )_(2)=(1,-1,0,1),-|||-(alpha )_(3)=(-1,1,1,0) 正交化.

题分）用施密特正交化方法将下列向量组标准正交化alpha_(1)=(1,0,-1,1)^T,alpha_(2)=(1,-1,0,1)^T,alpha_(3)=(

设向量组 (alpha )_(1)=((0,1,1))^T, (alpha )_(2)=((1,0,1))^T (alpha )_(3)=((2,1,0))^T

设向量组(alpha )_(1)=((1,0,1))^T，(alpha )_(1)=((1,0,1))^T，(alpha )_(1)=((1,0,1))^T不能

设向量(alpha )_(1)=((1,1,-1))^T (alpha )_(2)=((0,2,1))^T,(alpha )_(1)=((1,1,-1))^T

若向量组(alpha )_(1)=((1,1,1))^T (alpha )_(2)=((0,1,1))^T (alpha )_(3)=((0,0,1))^T能由

设向量组 alpha_1 = (1,1,1), alpha_2 = (0,1,2), alpha_3 = (1,0,-1)，那么该向量组的秩为:A. 3B

设向量组 alpha_1 = (1,1,1), alpha_2 = (0,1,2), alpha_3 = (1,0,-1)，那么该向量组的秩为:A. 2B

判断题（共10题，每题2.00分）1.向量组alpha_(1)=(1,1,1,1),alpha_(2)=(1,1,1,0),alpha_(3)=(1,1,0,0
