This went around Tumblr at the beginning of February, but I thought I would share it in case some readers haven’t seen it yet.
Asking Google for the graph for a particular formula produces this:
If you want to watch it rotate endlessly, you can go here or type
Graph for 5+(-sqrt(1-x^2-(y-abs(x))^2))*cos(30*(1-x^2-(y-abs(x))^2))
in the search bar.
Google will apparently do all your math homework for you. ; ]
Happy Valentine’s Day!
