Remember the simple trick of typing in this query ‘Do a Barrel Roll’ and the entire results page on Google turned upside down and back again. Well this Valentine’s Day, someone has figured out a way to enter a mathematical equation and get a graphical output which is heart shaped.

### The Equation to Google’s Heart!

Just enter the following equation into Google Search and hit the search button.

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

The equation is translated into a Graph which shows up in the shape of a heart. This feature is not a very well known feature of Google. You can check out more such Google search features here.

Google does have some weird Easter eggs, but this was probably not the doing of a Google programmer. If you play around the values in the equation, the output starts to change. So someone must have figured out a way to create this hear shaped design with the right values.

Do this search on wolfram alpha, it will give a much better shape….

Thanks. But not limited to Google. Try it on Wolfram|Alpha
