Using Matlab Create a vector $x$ of values from $0$ to $20,$ with a spacing of $\frac{}{100}.$ Define vectors $y$ and $z$ as

$y=xsin(x)$

and

$z=xcos(x)$

$($a$)$ Create an $x-y$ plot of $x$ and $y.$

$($b$)$ Create a polar plot of $x$ and $y.$

$($c$)$ Create a three$-$dimensional line plot of $x,y,$ and $z.$ Don't forget a title and labels.
