You are my Valentine:L-ove equation by Google

Google has come up with a great idea this Valentine. it has developed an equation that pasting into Google's search engine generates an exciting love graph. Technology lovers and math feeling amorous are creating  so much ruckus for this Valentine on social media sites   and Tech blogs. The mathematical equation that generates the love graph follows as: 

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

Entering the above equation into Google's search engine brings heart displaying a graph exactly at the center.
