Let $x$ be a column array of $201$ points evenly spaced between $0$ and $10.$ Write Matlab code to perform the following. Turn in your code listing as well as images. The images may be screen shots, but try to crop if you can.

$($a$)$ Plot $e^{-|x|}sin(x)$ at the points of $x.$

$($b$)$ Plot $e^{-(\frac{x}{2}{)}^2}cos(x)$ at the points of $x.$ This one is a little tricky, so think of it in small steps.
