How to Draw Functions Online in Google

You can draw any mathematical Function easily in Google. Google is awesome. This post shows how to draw functions from the basic.
    You should type your function in Google search box according to following one of way.

Important:  

• You should type your function in Google. Other search engines still not provide this facility.
• If you want to get function f(x) = 3x. Then when you type "3x" in Google search box this will not work. But when you type 3*x this will work. This problem will happen only few situations and you can avoid this by using "*" (multiplication) notation between variables and numbers.

There are several ways to do this: 
(click on any image)

Graph will display as follow. You can zoom in and zoom out drawn function and you can get any X and Y coordinates using mouse pointer. 

If you want to Draw 2 or more functions in same Graph:

Use comma to separate two functions.

Two functions will display by different colors. If you want to get any X and Y coordinates, first you have to select function which you want. You can select it by clicking the colored point in the right side above. 

Important : Above all functions are drawn in 2D plane. They are drawn in X , Y axis. If you want to graph a function in 3D plane you have to use another variable in the function. 3D graph will display with motion. (Note :  You should have update your web browser with latest version.)

Ex: y - abs(x^2) or z = y - abs(x^2)

Test these Functions for fun :

Function: sqrt(cos(x))*cos(300*x) + sqrt(abs(x))-5) * (6-x^2) ^.04

Function: 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 5

Function: sqrt(cos(x))*cos(300x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01, sqrt(6-x^2), -sqrt(6-x^2) from -4.5 to 4.5 

Function: 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
