Google 3D Graph

A new Google Search WebGL function allows for plotting 3D graphs in search results. This new feature provides an interactive version of Google’s graphing calculator functionality released last December. As Google recently blogged, “Just type any real two variable function into Google to see a dynamic, interactive, three dimensional plot. Click anywhere in the graph to rotate it to check out different angles, or scale the view by zooming in or out, or by editing the range in your equation or in the lower-right legend box.”


Some functions to try:
  1. sqrt(x*x+y*y)+3*cos(sqrt(x*x+y*y))+5
  2. 5000-140*(x*x+y*y)+(x*x+y*y)^2
  3. sin(x^2+y^2)/(abs(x*y)+1) from -2.5 to 2.5
  4. tanh(y(y^4+5x^4-10(x^2)(y^2))/(x^2+y^2)^4)
  5. (x^2+((3 y)/2-(x^2+abs(x)-6)/(x^2+abs(x)+2))^2)-36
  6. sin(5.5x)*cos(5*y)+x*x+1 x is from -1 to 1, y is from -1 to 1, z is from 0.1 to 2.8
  7. 100-3/(sqrt(x^2+y^2))+sin(sqrt(x^2+y^2)), x is from -10 to 10, y is from -10 to 10, z is from 85 to 101
  8. 5 + (-sqrt(1-x^2-(y-abs(x))^2))*cos(30*((1-x^2-(y-abs(x))^2))), x is from -1 to 1, y is from -1 to 1.5, z is from 1 to 6
  9. sqrt(x*x+y*y)+50*tan(sqrt(x*x+y*y))
  10. exp(-((x-4)^2+(y-4)^2)^2/1000) + exp(-((x+4)^2+(y+4)^2)^2/1000) + 0.1exp(-((x+4)^2+(y+4)^2)^2)+0.1exp(-((x-4)^2+(y-4)^2)^2)
  11. sqrt(cos(3*x))*cos(100*y)+1.5*sqrt(abs(x)) + 0.8 x is from -1 to 1, y is from -1 to 1, z is from 0.01 to 2.5
  12. sqrt(x*y+y*y)+3*sin(sqrt(x*x+y*y))+5 from -20 to 20
  13. sqrt(x*x+y*y)+3*tan(sqrt(x*x+y*y))+10
  14. x^2+y^2+x*y*sin(x+y) from -20 to 20
  15. 1/(sin(abs(x)+x)-cos(abs(y)+y))
  16. sin(5.5x)*cos(5*y)+x*x+1
