# Pi Day!

I had to. I’m so sorry.

Pi Day (sung to the tune of Rebecca Black’s Friday)

March 14th, waking up in the morning
Something’s goin’ down, but I can’t tell what
Gotta pack my bag, gotta go to class
Takin’ a glance at the calendar
Lookin’ at the date, gettin’ all excited
Gotta go get my math homework
Gotta do my trig, Gotta do geometry

Seeing circles on the page
Circumferences are all the rage
e, phi, zeta, K,
Which constant should I use?

It’s Pi Day, Pi Day
Gotta get down on Pi Day
Everybody’s lookin’ out for the area, area
Pi Day, Pi Day
Doin’ math on Pi Day
Everybody’s solvin’ problems for the area

Algebra, algebra (yeah)
Calculus, calculus (yeah)
Math, math, math, math

1:59 is the time we wait for
Gotta celebrate, best day of the year
Think circumference
I got this, you got this
Just type it, calculate it
Now you know it

Seeing circles on the page
Diameters are all the rage
e, phi, zeta, K,
Which constant should I use?

It’s Pi Day, Pi Day
Gotta get down on Pi Day
Everybody’s lookin’ out for the area, area
Pi Day, Pi Day
Doin’ math on Pi Day
Everybody’s solvin’ problems for the area

Algebra, algebra (yeah)
Calculus, calculus (yeah)
Math, math, math, math

Yesterday was boring, boring
But today is Pi Day, Pi Day
We-we-we so excited
We so excited
We gonna do some math today
Tomorrow it’s over
But July 22nd’s soon
I don’t want this party to end

3.14159
So useful of a number
Transcendental
See spheres, find volumes
Wit’ my pi up on my side
In my free time I do some geometry
Pi r squared, r squared, wanna cheer
Check my date, it’s Pi Day, it’s a great day
We gonna do math, c’mon, c’mon, y’all

It’s Pi Day, Pi Day
Gotta get down on Pi Day
Everybody’s lookin’ out for the area, area
Pi Day, Pi Day
Doin’ math on Pi Day
Everybody’s solvin’ problems for the area

Algebra, algebra (yeah)
Calculus, calculus (yeah)
Math, math, math, math
It’s Pi Day, Pi Day
Gotta get down on Pi Day
Everybody’s solvin’ problems for the area
Pi Day, Pi Day
Doin’ math on Pi Day
Everybody’s solvin’ problems for the area

Algebra, algebra (yeah)
Calculus, calculus (yeah)
Math, math, math, math
Everybody’s solvin’ problems for the area

Difficult to do because HORRIBLE SONG. Pi deserves better, so here’s my other math-related parody.

# Cake is a Lie, Pi is a Constant

Oh look, it’s Pi Day.
Have you heard, then, of Tau Day?

“The true circle constant is the ratio of a circle’s circumference to its radius, not to its diameter. This number, called τ (tau, is equal to 2π, so π is 1/2τ—and March 14 is thus Half Tau Day. (Of course, June 28, or 6/28, is Tau Day itself.) Although it is of great historical importance, the mathematical significance of π is simply that it is one-half τ.”

Interesting notion. Canadian news websites: reporting the slightly quirky version of Pi Day for all of us to enjoy.
