I was thinking, as x increases positively or negatively, the y values (angles) repeat multiple times, making the function many-to-one. In this case, we're mapping all the real numbers, to a subset of the y-axis. Am I mistaken? AG * *Arctan(1) = the angle whose tangent = 1. Isn't this angle 90 deg or pi/2? So your plot seems wrong, but it's what is on the Internet. AG * *That's wrong. Arctan(1) = pi/4, which is what the plot indicates. But I still think the plot keeps repeating as x increases or decreases.

Whereas tangent 0 degrees = tangent 360 degrees = 0, and arctan 0 degrees = 0, I thought arctan 360 degrees is also 0, but it apparently isn't. This is how I concluded y = arctan(x) is many-to-one.
