## How do I solve this eigenvalue question?...

Maple 17

The matrix:

<3,-2,-1,2,0>;

<11,4,-8,2,7>;

<0,0,2,0,0>;

<3,3,-4,3,3>;

<-8,4,5,-4,-1>;

has eigenvector:

<2,0,-1,0,1>

Find its corresponding eigenvalue.

(Hint: you don't need to find all the eigenvalues and eigenvectors to answer this question.)

Steps and the solution will be greatly appreciated. thanks!

## principal arguments and moduli of the 5 ...

Maple 17

Hi,

New to maple and I have 2 questions that I'm stuck on.

1) Find the principal arguments of the 5 roots of the polynomial

and enter a decimal approximation to the largest principal argument in the box below.

ans: 2.589502038

2) Find the moduli of the 5 roots of the polynomial

and enter a decimal approximation to the largest modulus in the box below

ans: 2.34880159160143

I dont really know what to write in maple to get the answer. So, if someone could help me out that would be really great. cheers
