exp(x)

So there's this party, right? A party of functions! All of the functions are there: e^x, πr^2, i^2, even some old-school guys like |x|. Anyway, poor e^x is alone in a corner, acting all morose. His good friend 2^x comes over and says, "What's the problem? Come on, integrate yourself into the party!" And e^x looks at him and he says, "Why? It's not going to make a difference!"
