If I were to write e to the minus 1 half times a, that's the same thing as e to the a to the minus 1 half power, right? If you take something to an exponent and then take that to an exponent, you can just multiply these exponents. So likewise, this could be rewritten as, this is equal to 1 over the square root of 2 pi sigma squared, which is just the variance. 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?
