Today is Pi Day, but you knew that already. To celebrate the bandwagonesque nature of this day, the mathematical constant π, we're posting our favorite mathematical equations set to song after the jump.
But first, some trivia:
- Pi is the symbol for the ratio of the circumference of a circle to its diameter.
- With the use of computers, Pi has been calculated to over 1 trillion digits past the decimal.
- Pi is an irrational and transcendental number meaning it will continue infinitely without repeating.
- The symbol for pi was first used in 1706 by William Jones, but was popular after it was adopted by the Swiss mathematician Leonhard Euler in 1737

She recovered for the next 24 digits but then it went to hell in a handbasket when she missed out the next 22 digits completely before finishing with a precise rendition of her final 37 digits."
