Google is embracing the spirit of Valentine’s Day… with a nightmarish mathematical equation.

But thankfully, the formula, if typed into the search facility, produces a baby blue love heart, Mashable revealed.

To try it out yourself, paste in the following:
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

It’s the latest “Easter Egg” offering from the search engine giant, which brought winter weather to desktops across the world at Christmas.

Typing “let it snow” prompted digital snowflakes to start falling across your screen. You could wipe away the frost by using your cursor as an ice scraper or pressing the “defrost” button, which appeared in place of the blue “search” button.

In November, typing “do a barrel roll” sent search screens into a 360-degree spin. The treat was a reference to the 1997 videogame Star Fox 64 and the effect was like a fighter pilot executing an in-flight barrel roll in the wild blue yonder.
