Pi Day Videos – Song & Limerick

March 14 is Pi Day. Mathematicians, teachers, and math geeks around the world celebrate.

Especially at 1:59. That’s when the date and time is 3/14 1:59 – pi to 5 digits.

My treat for you last year was a photo of pi decorated cookies. This year the treat is even more delicious – a Pi Song from Vi Hart and a Pi Limerick from me.

Vi Hart can sing!

You can’t deny Vi Hart has mathematical and creative talent. But who knew she had a musical voice!

My Pi Limerick – because I can’t sing.

I can’t carry a tune in a bucket much less associate digits with musical notes.

But I can remember pi to 5 decimal places with the help of this limerick:

Happy Pi Day, y’all!

  1. My highschool Trig teacher (Mr. Campbell — a good man!) taught us to remember the digits of pi by chanting the rhyme ‘sine, cosine, cosine, sine, 3.14159’.

    The order of sines and cosines refers to how to apply Euler’s formula to sine [e.g. sin(x+y) = sin(x)cos(y) + cos(x)sin(y)]. Though I had to look up the formula, I have *never* forgotten the rhyme!
