An exponential walks into a bar. He pulls up a bar stool sits down and asks the bar man for a pint.
Over in the corner theres a large group of functions, sines, cosines logs all sitting around having a laugh telling jokes and sharing stories.
The bar man comes over and asks the exponential why he’s all alone and not over having fun with the other functions.
The exponential answers in a low voice, “I tried to integrate but nothing happened”
