Anyone else feeling left out? I poked the link on my phone and just got search results (safari). Same thing in mobile chrome even after "request the desktop site". It wasn't until I got to work and saw all of the comments that I figured out what was going on.

iOS (iPhone at least) Safari: go to https://www.google.com/search?q=x*sin(y), tap the address bar, scroll up, and tap Request Desktop Site.

But has it always done 3D? I was completely unaware!

apparently before 2013 as shown in this 'google boobs' video: https://www.youtube.com/watch?v=YQjNpFCjfKE

I guess, we're flooding the maths-render servers.

Not sure exactly how it works but if you disconnect from the internet you can still change the x and y ranges and have it redraw so the render is client side.

It uses client-side rendering, WebGL I think.

Very nice. Why have you posted it?

So we all would waste 10 to 20 minutes putting in functions.

Search in Google following for Batman: 2 sqrt(-abs(abs(x)-1)*abs(3-abs(x))/((abs(x)-1)*(3-abs(x))))(1+abs(abs(x)-3)/(abs(x)-3))sqrt(1-(x/7)^2)+(5+0.97(abs(x-.5)+abs(x+.5))-3(abs(x-.75)+abs(x+.75)))(1+abs(1-abs(x))/(1-abs(x))),-3sqrt(1-(x/7)^2)sqrt(abs(abs(x)-4)/(abs(x)-4)),abs(x/2)-0.0913722(x^2)-3+sqrt(1-(abs(abs(x)-2)-1)^2),(2.71052+(1.5-.5abs(x))-1.35526sqrt(4-(abs(x)-1)^2))sqrt(abs(abs(x)-1)/(abs(x)-1))+0.9 link…

Wolfram Alpha does a pretty amazing job of taking an existing graphic and turning back into a graph-able equation... eg:

They also have some neat ones for Pythagorean's Theorem, the area of the circle, and other questions:

Thanks for sharing this. Every single day I convince myself that I am not wasting my time by going on HN and posts like these are the reason I find something useful and meaningful. This is something I can share with my 9 year old son who is showing keen interest in Maths. Though the stuff presented here is still pretty advanced for him to grasp, but sharing this will help him immensely to keep pursuing his mathematical interest.

Batman Graph rocks !!

Google has done math in the search for a while. It is also my go to place for unit conversions.

Speaking of which, miles per hour get converted in m/s, which is not very useful
