And I'm just playing around with the formula, because I really want you to see all the ways that it, you know, maybe you'll get a little intuition. And I encourage you to email me if you see some insight on why this exists and all of that. But once again, I think it is cool that all of a sudden we have this other formula that has pi and e in it, and this is really just, you know, this is what the central, you know, so many phenomenon are described by this. And once again, pi and e show up together, right? Just like e to the i pi is equal to negative 1 tells you something about our universe. But anyway, I could rewrite this as e to the x minus mu over sigma squared, and all of that to the minus 1 half. Something to the minus 1 half power, that's just 1 over the square root, which is already going on here.
