[理工] 線代
1.If a nonzero vector v is in the null space of a linear operator
T,then v is an eigenvector of T.
(T):eigenspace of T = nullspace of T-入I
這樣答案是錯吧??
2.Every square matrix has a complex eigenvalue.
(T):why??不可以只有real嗎?
2
3.If (t-4) divides the characteristic polynomial of A,then
4 is an eigenvalue if A with multiplicity 2.
(F):am(入=4)=2 這樣不是對嗎?? 怎是錯...
4.If A is an n*n matrix,then the sum of the multiplicities
of the eigenvalues of A equals n.
(F):是因為不一定等於n嗎?
5.The standard vectors are eigenvectors of a diagonal matrix.
(T):這要怎麼證??

我想請問一下 47 和 48的問法差異在??
