It’s the first day of our GeoGebra training tomorrow, so let us celebrate Valentine’s day in advance. To all who are **mathematically in love**, you can celebrate Valentine’s day by doing the following:

- Copy this: sqrt(cos(x))*cos(300x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01, sqrt(6-x^2), -sqrt(6-x^2) from -4.5 to 4.5
- Go to Google.com
- Paste it in the Google search box and click the Search button. You will see the graph below.
- Send the graph to your loved one.

Surprised? Yes, Google Search has now the ability to plot mathematical functions.

Happy hearts day in advance!

Let’s make the heart red 🙂

sqrt(6-x^2), (1.5 sqrt(cos(x))*cos(300x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01,-sqrt(6-x^2) from -4 to 4

(It doesn’t work in IE for me)

This is brilliant although I have absolutely no idea how you would go about finding such a function?!?

Me too. When I first saw the graph, I was thinking about piecewise functions.
