But ex Is So Special...
There is a big calculus party one night, and all the functions had been invited. ln(x) is talking to some trig functions, when he sees his friend ex sulking alone in a corner.
ln(x): "What's wrong ex?"
ex: "I'm so lonely!"
ln(x): "Well, you should go integrate yourself into the crowd!"
ex looking up in tears: "It won't make a difference!"
