Graphing Explorations
By Annie Sun
Let's look at the following equations and their graphs:
This is the unit circle with the origin at (0,0) and a radius of 1
We begin to notice a difference in graphs for when n is odd and when n is even.
When n is odd...
Notice that the graph begins as a curve and becomes more angular. It also look like the line y = x is a diagonal asympotote.
When n is even...
Notice as n increases the graph also begins as the unit circle and then becomes to look like a square (although the corners are still slightly rounded)
So, what do we expect the graph of to look like from the pattern of graphs above?

We have looked at the graphs of when n are odd and even whole numbers.
Now what if we make the n values negative?

Here are some graphs of negative even n values
Notice they seem to be the outward graphs of the positive n even values. Let's put them together and see what we get...
It looks like the corresponding positive and negative n values have the same curvature. It also looks like they have the same asymptotes at y = 1, y = -1, x = 1, and x = -1.
There are still many more values of n that we could use and graphs that can be compared, but to keep it simple, I have only displayed integer values of n. The conclusion that can be made from the equations and graphs above, is that as n approaches infinity in either direction, the graphs get closer to the aymptotes.
