But you don't understand how valuable my time is, not watching.

That wasn't so bad, but the "my true love gave to me" bits were a bit ear-splitting.

1 is any other number to the power of zero? Sorry, ZERO to the power of zero is undefined. See me after class.

Yeah, I have that problem when I use my calculator. It keeps giving me "1", even when it can say other things are undefined.

Depends on the context and discipline, and I don't think any mathematician would fault someone for using 0^0=1 when necessary. Except for fucking Cauchy, I mean.

You define integer exponentiation by A^B = (the number of functions from a set of size B to a set of size A). 0^0 is the number of function from a set of size 0 (the empty set) to the empty set. There is exactly one such function, and it is called the empty function.

You might say "oh, but the function x^x is discontinuous on (-inf,0], and so 0^0 shouldn't be defined." If you believe this, then you also believe that (-1)^(-1) is undefined, so (surprise), -1 has no multiplicative inverse and hence rational numbers are not a field (oops).

Sorry, as much as I like math I'm never going to like these.

I hate math, but I actually thought this was pretty cool.

I like math, and I like this video, but some of the singing is pretty bad. Not "let's enjoy the badness" bad, just regular unwelcome bad.
