Don’t be a pervert. I’m talking about the sextic equation, or the heart equation. Remember college algebra? Remember how this equation graphs a circle:

[pmath size=12]{(x-h)^2+(y-k)^2=r^2}[/pmath]

Well, there has to be a function out there that describes a heart, right? At least that’s what I was asking myself during church today. So google I did, and voila! Here a couple:

[pmath size=12]{x^2+(y-sqrt{delim{|}x{|}})^2=n, where n=3}[/pmath] ^{1}

My favorite comes from Wolfram ^{2}, which is known as the sextic equation:

[pmath size=20]{(x^2+9/4y^2+z^2-1)^3-x^2z^3-9/80y^2z^3=0}[/pmath]

Happy Valentine’s Day!

I will mention that yesterday’s sermon was quite good, and you missed it by thinking about math the whole time! ðŸ˜› Love you!

Rob. Sarah has gotta love ya. Hope you two had a great Valentines Day.

You are adorable. I love it!

Yikes, your question about remembering college algebra was a bit of a head scratcher. I had to think back about that. Can’t say any prof taught us the equation for a heart. Pretty cool.

I think this could be made into a great Valentine’s card somehow.

You’d have to be the biggest geek in the world to write this equation on a Valentine’s card and hand it to a loved one. I guess I’m gonna try to next year as a joke. It’s no secret that I’m handy with my graphing calculator. But I doubt my g/f will appreciate the gesture.

Whoa! That’s some hard core algebra for Valentine’s Day! I didn’t know that they also coined the sextic equation as the heart equation. This is cool stuff.
