x*sin(y)
- ColinWright 11y agoVery nice. Why have you posted it?
- sgt 11y agoProbably to show us that it's possible. I didn't know Google Search accepted equations.
- keerthiko 11y agoNote that the search is not even an "equation" (that would be z = x*sin(y) ). Google always graphed equations -- I often use a google tab like a nice low-memory-footprint version of MATLAB basically -- but I didn't know it assumed the third axis when you created a non-linear expression and made it an equation.
- Lawtonfogle 11y agoSo we all would waste 10 to 20 minutes putting in functions.
- chrisBob 11y agoGoogle has done math in the search for a while. It is also my go to place for unit conversions.
- kaoD 11y agoBut has it always done 3D? I was completely unaware!
- return0 11y agoapparently before 2013 as shown in this 'google boobs' video: https://www.youtube.com/watch?v=YQjNpFCjfKE https://www.youtube.com/watch?v=YQjNpFCjfKE

- tormeh 11y agoI like the axes. Those are usually really badly visualized in most 3D plotting software. Just indicate the origin a bit better and we're gold.
- nodata 11y agoThe link doesn't work for me (Firefox). I have to hit Enter in the search box for it to work.
- MereInterest 11y agoChrome here, with the same issue.
- contradictioned 11y agoI guess, we're flooding the maths-render servers.
- ramblerman 11y agolol, I think you're overestimating HN traffic just a bit here. Adding a hash solves the double enter https://www.google.com/?#q=x*sin(y) https://www.google.com/?#q=x*sin(y)
- _lce0 11y agolol, I think he's underestimating the Google server power a bit there :)
- tim333 11y agoNot 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.
- witty_username 11y agoIt uses client-side rendering, WebGL I think.
- CyberShadow 11y agoCompare the submitted URL: https://www.google.com/?q=x*sin(y) with: https://www.google.com/search?q=x*sin(y) The resource is still the index page, not /search for the search results page; the query is simply prepopulated.
- ddebernardy 11y agoIf any Googler is around, it would be nice if one could do 4d representations as well. (As in 3d that evolves in time, with a slider to go back and forth in time.)
- nashashmi 11y agoI believe Google will answer "baby steps." Until then, go and google up that elsewhere.
- morpheous 11y agoOh wow!, just wow!!. Maths FTW!
- thwd 11y agoMildly interesting, if you search for: x * tanh(y) you get the graph for: x * (exp(y)-exp(‑y))/(exp(y)+exp(‑y)). [Edit: asterisks on HN are hard]
- noel_ 11y agoJavaScript doesn't have tanh built in, so you have to use an approximate: http://stackoverflow.com/questions/6118028/fast-hyperbolic-tangent-approximation-in-javascript http://stackoverflow.com/questions/6118028/fast-hyperbolic-t...

- _lce0 11y agonow we just need to 3d print those
- kardos 11y agoAxis labels? Anybody?
- pekk 11y agoReminds me of Wolfram Alpha.
- avinassh 11y agoSearch 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 to the same: http://bit.ly/1G0rLgk http://bit.ly/1G0rLgk

- teh_klev 11y agoNow I challenge you to drop in the Eye of Sauron :)

- BMarkmann 11y agoWolfram Alpha does a pretty amazing job of taking an existing graphic and turning back into a graph-able equation... eg: http://www.wolframalpha.com/input/?i=graph+looks+like+batman http://www.wolframalpha.com/input/?i=graph+looks+like+batman http://www.wolframalpha.com/input/?i=graph+looks+like+bart+simpson http://www.wolframalpha.com/input/?i=graph+looks+like+bart+s...
- acadien 11y agoI feel like these are special cased, searching for: graph looks like <object> with any random object turns up junk. Edit: then again it does work with Obama but not with Richard Nixon.
- tempodox 11y agoHow do you get a page where you can edit the expression graphed?
- amelius 11y agoWhile this is nice, I don't like the idea of one company being the one-stop-shop for all of our knowledge.
- scrollaway 11y agoOur civilization is doomed. Society will fall apart because Google decided to do 3d plots in their search engine.
- raverbashing 11y agoNext thing you know, someone will be asking how to do it with JQuery. Not JS, JQuery
- upofadown 11y agoI think it could be argued that the graph of a function isn't actually knowledge... but otherwise I agree there is a potential problem here...
- nashashmi 11y agoI think it is okay for Google to send you that one answer so that you no longer need to do anymore searching. They scour the web and extract the simple answers that you require. (Google Customer Service: Did you find what you were looking for?) YES! There are other websites that do this as well, and do it better, but they should be leaping to more complicated stuff once they have "plucked the low hanging fruits" for the establishment of their services. This is the kind of democratization of knowledge and resource that the open web is all about.
- chrisBob 11y agoAnyone 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.
- oblio 11y agoSame here, Chrome/Ipad :|
- rbp7 11y agoIf you're on android chrome, try switching to desktop mode and then press enter if it still doesn't show up. Worked for me.
- 0942v8653 11y agoiOS (iPhone at least) Safari: go to https://www.google.com/search?q=x*sin(y) https://www.google.com/search?q=x*sin(y), tap the address bar, scroll up, and tap Request Desktop Site.
- smaili 11y agoFor those having issues, adding the hash should do the trick: https://www.google.com/?#q=x*sin(y) https://www.google.com/?#q=x*sin(y)
- LaFolle 11y agoGiving competition to Wolfram Alpha. Very interesting.

- sk2code 11y agoOnly works in Chrome.
- Bouncingsoul1 11y agoWorks perfectly in Firefox 36.0.1 on Ubuntu

- Sir_Cmpwn 11y agoWFM in Firefox 37.0.1 on Arch Linux.
- TheHypnotist 11y agoIt, uh, works in IE.
- dazmax 11y agoThe search doesn't actually find pages with x * sin(y), though. Even on verbatim mode the best it does is x = sin(y).
- eccstartup 11y agox*y is more beautiful. It is a perfect hyperbolic surface.

- sk2code 11y agoThanks 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 !!

- wnevets 11y agoaccording to the EU this is an antitrust violation?
- jarin 11y agoThis is kind of unrelated, but when you grab the graph with your mouse and make circles, the whole graph rotates along the line of sight axis. I've noticed this with many 3d things. Why is that?
- HanyouHottie 11y agoIt's easier to understand if you take the motion of a circle to the extreme: Rotate the graph 90 degrees to the right, then any amount up or down, then 90 degrees back to the left. By rotating 90 degrees first, you changed the axis of the second rotation to be the plane normal (perpendicular) to the view axis, i.e. the view axis itself. If you instead drag in smaller circles, then each rotation only contains a small component of rotating that plane so the rotation is slower.
