Compare using &gt;,&lt;, or =. 3/5___7/10<br> plzzzzz help meeeeee
aniked [119]

3/5 > 7/10

Reasons:

3/5 = 6/10 because 3/5 x 2/2 = 6 / 10

6 > 7 so 6/10 > 7/10

Therefore: 3/5 >7/10

Exercise 3.7.4: let a = 2 1 0 0 2 0 0 0 2 .
swat32

With

\mathbf A=\begin{bmatrix}2&1&0\\0&2&0\\0&0&2\end{bmatrix}

we have

\det(\mathbf A-\lambda\mathbf I)=\begin{vmatrix}2-\lambda&1&0\\0&2-\lambda&0\\0&0&2-\lambda\end{vmatrix}=(2-\lambda)^3

so \mathbf A has one eigenvalue, \lambda=2, with multiplicity 3.

In order for \mathbf A to not be defective, we need the dimension of the eigenspace to match the multiplicity of the repeated eigenvalue 2. But \mathbf A-2\mathbf I has nullspace of dimension 2, since

\begin{bmatrix}0&1&0\\0&0&0\\0&0&0\end{bmatrix}\begin{bmatrix}x\\y\\z\end{bmatrix}=\mathbf 0\implies x=0\text{ or }y=0

That is, we can only obtain 2 eigenvectors,

\begin{bmatrix}1\\0\\0\end{bmatrix}\text{ and }\begin{bmatrix}0\\0\\1\end{bmatrix}

and there is no other. We needed 3 in order to complete the basis of eigenvectors.
