Use numpy and mathplotlibpyplot

Write a calculate$\_$LJ function that includes parameters for setting

and

$.$

After writing the function, perform a set of calculations with

and

both equal to one. Using these values, calculate the Lennard Jones potential energy for a range of distances, r$,$ from r $=0\mathrm{.}1$ to r $=5$ in increments of $0\mathrm{.}1.$ Save your results in a list.

Next, perform a set of calculations where

is equal to $2$ and

is equal to one. Then set

equal to $1$ and

equal to two. For each set of calculations, save your result in a list.

Visualize all three results on a graph using matplotlib.

In your submission, include a markdown cell that contains a reflection $($at least five sentences$)$ on your approach and observations.
