Pi is that 3.14 number, and it just goes on and on.
You use pi to find the area of a circle.
In eighth grade Sister Rose made us memorize the quadratic formula.
(this image is fuzzy like my memory)
I have no idea when one would use the quadratic formula.
In geometry class, we had to write out a bunch of proofs,
to make sure that shit that mathematicians have known
since the days of the ancient Greeks is still true.
Sine and Cosine and Tangent…they are ratios of some sort.
You use them for trigonometry.
You do derivatives in calculus, but I don’t remember why.
In real life I can do basic arithmetic to balance my checkbook
and proportions to figure out how many minutes
it takes me to jog a mile.
I calculate percentages for tips,
but I zone out when it’s time to split the bill at a restaurant.
Most important of all, I use fractions for baking,
like when I can’t find the 1/4 cup,
so I scoop out 2/8 of a cup of flour instead.
