So, you have a *geek girlfriend* or want to impress some *geek girl*. You can try following tip or I should say inadvertent **Google easter egg**.

Its pretty simple, just ask her to search following string on Google:

`(sqrt(cos(x))*cos(200x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01, sqrt(9-x^2), -sqrt(9-x^2) from -4.5 to 4.5`

For impatient or lazy, curious dudes here is a shortcut link to this **Google Graph Trick**.
