How to Construct a GeoGebra Heart Graph

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 

(x^2 + y^2)^3 -x^2y^3 = 0.

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 ManilaGeoGebraTube, 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.
