## Introduction

The equations for several curves
were mentioned in the video
Why π is in the normal distribution.
I thought plotting these curves would be an interesting project.

Use graphics.py.
For more information click HERE
.
(download, install, documentation, etc.)

Use Cartesian coordinates centered in the graphics window.
Scale and center the curve values to fit the window.

## Project #1

Create your own Cartesian plot function and plot the following curves.
(x,y origin in the center of the graphics window. Also draw the x,y axes.)

*Note: This is a problem in translating equations into code
and scaling data.*

Y = 1/(1 + X^{2})

Y = 1/(1 + X^{4})

Y = e^{-x2}

Y = e^{-x4}

Y = e^{-1/e}(|X| + 1/e)^{-(|X| + 1/e)}

Y = (sin(πX)/(πX))^{2}

Y = sin(X)

## Project #2

Plot the curves using a Python plot package.

*I suggest you use the pyplot or related modules.
