$2\mathrm{.}1$ Predict what will be displayed when the following Python mands are executed. Then try them. Explain how they work. Use h resources as needed.

import numpy as $np$

$A=np$ matrix $(\text{'}1,2,3$;$2,4,6$;$3,2,1^{\text{'}}$

$pr{\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}(A)$

At $=$ A$.$transpose $()$

print$($At$)$

$A1=A[$:$,2]$

print$($A$1)$

$nm=np*{\displaystyle \underset{?}{\overset{?}{}}}(np*diag(A))$

print $(nm)$

$Ad=np*delete(A,1,0)$

print$($Ad$)$

$2\mathrm{.}2$ Create program statements in Python that compute a vector values based on the following formulas:

$($a$)y=\frac{6t^3-3t-4}{8sin(5t)},0\mathrm{.}1t0\mathrm{.}25$

$($b$)y=\frac{3t-2}{4t}-\frac{}{2}t,1t5$

where $t$ is a vector of $10$ values in the range prescribed. Create a
