Again, our awesome Google add a new feature to the search engine. That is Instant Graphing functionality to search results which allows us to plot numerous mathematical functions, right on Google.com’s search results page. Simply head over to Google.com and type in the function of your choice in the search box. Instantly, an interactive graph will pop up, complete with zoom buttons, pan options and the ability to see the x and y values for every single dot on the function’s line. This function is similar to what Wolfram Alpha website can do, but we cannot refuse the fact that Google is more familiar for us to use. Announced on its official blog, Google hopes that students and math lovers around the world would find the new functionality “magical” and bring back the fun in making graphs.
Now we don’t need to write down on graph paper as high school teachers always ask student do that at math class.
Let’s check some examples. Enter cos(pi*x) * x^2 in the google searching bar, and you will find:
Here I found in the internet a geeky stuff that you may find interesting. Perhaps this could be a way a geek ask a woman for a date 😛
The above graph can be plotted using the following mathematical expression: (sqrt(cos(x))cos(200 x)+sqrt(abs(x))-0.7)(4-x*x)^0.01, sqrt(9-x^2), -sqrt(9-x^2) from -4.5 to 4.5
Or try this awesome plotting by googling:
1.5sqrt(-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)+(4.5+0.75(abs(x-.5)+abs(x+.5))-2.75(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))
and see the result! *click zoom out button if not properly appears*

Now that Batman function was cool!
