Initially, I was just going to post this picture and call it a day.
Then I made mistake and ended up with this picture below ...The new graph is missing the "+2" so I began to mess with it more since I thought it looked cool.
The next pictures were really interesting since all I was doing was changing signs or changing the values of the numbers in the formula. I wanted to just flip the heart and it took me some time to figure it out. I solved my problem by keeping all the numbers the same but the signs were flipped. Next, I just messed with it more and got the following graphs.
Just in case anyone is wondering what program I used the program is Mathematica. It's a paid program but I get it for free since I am a student. For the math nerds, a heart is simply a cardioid I believe ,so if you look up cardioids on google you should get a polar representation of a heart like I did.
