We enjoyed creating a two dimensional heart graph and three dimensional heart graph using the Google search engine, but we can also construct a GeoGebra heart graph. In this post, we learn how to create a heart graph using GeoGebra. The equation of this graph is a lot simpler compared to the first two (well, because it is in factored form).

**How to Construct a GeoGebra Heart Graph**

Open GeoGebra. You might want to display the *Axes* by pressing *Graphics* at the upper right of the *Graphics view* and then choosing the Axes icon.

In the Input Bar, type (x^2 + y^2 – 1)^3 – x^2y^3 = 0 and the press the Enter key on your keyboard. The equation you typed is equivalent to

.

The ^ stands for exponentiation in GeoGebra.

Change the color of the graph by clicking the graph and choosing the right color from the *Styling bar *at the upper left part of the *Graphics view*.

To those who are new to GeoGebra, it is a free dynamic mathematics software that can be used for teaching and learning mathematics. If you want to learn about it, I have created more than 50 GeoGebra tutorials now in version 4.2. Sample applets can be seen at the GeoGebra Institute of Manila, GeoGebraTube, and GeoGebra Applet Central.

Great site – really well put together with quality materials. I also notice you are the contact for the Geogebra Institute at UP Diliman. I lived for a while in the Philippines and as a math teacher in New Jersey I am very interested. Feel free to send me an email when you can. Maraming salamat po!

Thanks John. I am quite busy right now because I’m preparing leaving for Japan. I have passed all GeoGebra activities to my colleagues.
