Happy sextic (equation) day

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:


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:

{x^2+(y-sqrt{delim{|}x{|}})^2=n, where n=3} {1}

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

  1. I will mention that yesterday’s sermon was quite good, and you missed it by thinking about math the whole time! ๐Ÿ˜› Love you!

  2. 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.

  3. 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.

  4. 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.
