To anyone confused, watch this video. It is a graphical representation of e^(pi)(i). Imagine, then, graphing it with half of pi instead. It would result in a 90 degree rotation instead of 180 degrees. And what is 8 rotated 90 degrees? An infinity symbol.
Sometimes, humans should not be allowed to play with numbers. This is one of those times.
I’m missing the joke.
The joke is that the 8 gets rotated 90 degrees counterclockwise which turns it into an infinity symbol.
I’m by no means a mathologist or anything but I’m calling bullshit. Something times 8 is infinity? C’mon
e^(i pi/2) rotates a point 90 deg around the unit circle. The joke is that it simply rotated 8 by 90 degrees.
