A. 若 INCLUDEPICTURE ＼d "http://mooc1-api.chaoxing.com/ananas/latex/p/9997" ＼* MERGEFORMATINET 
中向量集S={u,v,w}中任意一个向量都不是其它向量的倍数,则S线性无关
B. 若{u,v,w}是线性无关集,则u,v和w不在 INCLUDEPICTURE ＼d "http://mooc1-api.chaoxing.com/ananas/latex/p/3847" ＼* MERGEFORMATINET 
中
C. 在某些情况下,4个向量可能张成 INCLUDEPICTURE ＼d "http://mooc1-api.chaoxing.com/ananas/latex/p/157705" ＼* MERGEFORMATINET 
空间
D. 若u和v属于 INCLUDEPICTURE ＼d "http://mooc1-api.chaoxing.com/ananas/latex/p/106387" ＼* MERGEFORMATINET 
,v不是u的倍数,则{u,v}线性无关
,|b|=2,且( )⊥a,则向量a和b的夹角是________度.
