Here's what a VPN can't protect you from (but you need to use it)

Google chart now in 3D

Google chart now in 3D

A few months ago, Google integrated charting into its search engine to help students and math enthusiasts with their homework.

This was quite useful and interesting for everyone, so various charts were created, such as Batman's characteristic logo and the like.

Now it is possible to make more complex charts in 3 dimensions (3D)!

Just type a function with two variables to see a dynamic, interactive, three-dimensional drawing. Click anywhere on the chart to rotate and view it from any angle, and you can zoom in and out with the wheel.

You can set variables in the lower right corner, or you can do so in the function you entered in the browser.

This 3D display feature is enabled by a technology called WebGL, which Google is using for the first time in their search. WebGL is a new web technology that brings hardware acceleration to display 3D graphics in a browser without the need to install additional software. This technology is currently supported on more modern browsers such as Chrome and Firefox.

Here are 3 examples that you can enter directly into the search box:

sqrt(x*x+y*y)+3*cos(sqrt(x*x+y*y))+5 from -20 to 20
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
tanh(y(y^4+5x^4-10(x^2)(y^2))/(x^2+y^2)^4)
