U + I = L0/e

(It’s the weekend before Valentine’s Day, and my boyfriend is home for the weekend from college. He is currently in advanced calculus, and we met in math class. He gives me flowers with a note.)

Boyfriend: “Read the note.”

(I open the note, it reads:)

Note:
y1=3D-=E2=88=9A(1-x^2)-x^(2/3)
y2=3D=E2=88=9A(1-x^2)+x^(2/3)
y3=3D-=E2=88=9A(1/4-x^2)
y4=3D=E2=88=9A(1/64-(x+0.5)^2)+0.65
y5=3D=E2=88=9A(1/64-(x+0.5)^2)+0.65
window: x min=3D-2, x max=3D2
y min=3D-2, y max=3D2

(I graphed it on my graphing calculator, and it ends up being a heart with a smiley face.)

Me: “You’re such a nerd sometimes, but I love you.”

Boyfriend: “Hey, I’m not such a nerd. That took me a whole half hour to do!”
