4.(20%)下面的問題共有四個子題,只要寫出每個子題的答案即可(不需寫出計算過程),例如
(a)β=1, γ=2。
Let a1 = [1 0 1 a]T , a2= [1 β 2 2]T, and as = [-2 3 γ -4]TFbethree vectors in R4,
where a, β, and γ are three real parameters, and denote A := [a1 a2 a3]
.
, where N denotes the set of all positive integers, then find positive integers β and
such that {a1, a2, a3} is a linearly dependent set.
