[理工] 線代
(1)Which of the following is a root of the function f(t).
(a)0 (b)pi/3 (c) pi/2 (d)pi
[ 7 1 -2 0 0]
[-1 2 1 0 0]
f(t)=det[ 4 3 2 2 2]
[ 2 2 2 2 2]
[ 2 1 0 cost 2]
我一開始想用降階解，但發現有點複雜，不知道有人知道
有更迅速的解法嗎
(2)The solution set of Ax=b is obtained by translating the
solution of Ax=0.
T:為什麼兩個解空間可以從N(A)得到?
感謝
