Liner Notes

And in the next installment of #countingwithmetalfoot we have a number you can't actually count, because it's part of the irrational numbers! Whee!

e is a great number. Ironically, the chord E was unharmed in the writing of this song but that's OK.

For those who don't know, I was a math major in university. This is my sorta thing to geek out about.

Lyrics

e

e is the sum of the infinite series from 0 to infinity of 1 over n factorial
e is a magical constant in mathematics, that's not just rhetorical

For e to the x is its own derivative
And e to the x is its own antiderivative as well
Yet e is not the sort of number you can count upon
e is irrational and as it goes that's just as well

e is a transcendental number, and that is something good to contemplate
e on the complex number plane helps sine and cosine to correlate

For e has a decimal expansion that will never end
e is a funky number for sure, I wish I could be its friend
Yet e is not the sort of number you can count upon
e is irrational and as it goes that's just as well

e is roughly 2.71828182845904523536028747135... that's all I wanna recite tonight
