I was trying to figure out how to write “æ” and I came up with a (what I consider to be) brilliant explanation.

First you draw f(x) = –sin(x) from the x values of –pi/2 to +pi/2. (erghhh how do i LaTeX within a blog post)

Then you draw an infinity symbol along the axis of f(x) = x, centered at zero. Or I guess a regular infinity symbol with a semimajor axis of pi/2, centered at zero and rotated 45 degrees counterclockwise? Hmm which way is better to say it? Is there a function that outputs the infinity symbol?

I AM HAVING SO MUCH FUN.

..Hey, wait… where are you going? Why are you closing this tab?

Ha! Nice explanation. But only useful for a fraction of the US population…

Nice approximation, Timothy 🙂
