Google has been making a lot of changes of late. Recently we saw the new Google Bar showing up on its home page, which allows users to easily navigate through the various services, including Google Plus, Gmail, News, and so on. Google has integrated yet another impressive feature into its search engine – a full graphing calculator.
Well, in case if your calculator dies, you can always rely on Google to use the graphing calculator to quickly perform the required operations. Students and math lovers can type in a function to the Google search bar, which will return an interactive, multi-colored graphical output.

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 you can plot mathematical functions right on the search result page – just type in a function and you’ll see an interactive graph on the top of the search results page,” Google Engineer Adi Avidor wrote on the Google blog.
Here’s an example of what you would see if you write cos(x) –
You can zoom in and out or pan across the plane. The x and y coordinates on the top-right corner of the graph follows your cursors to show the exact points. Users can also draw multiple functions by separating each function with commas. The feature can be best explained by simply trying it out. Search x/2, (x/2)^2, ln(x)
The results provided are powered by Wolfram Alpha, the self-described “computational knowledge engine” that launched two years ago. The computational knowledge engine helps Google’s search engine to plot the mathematical functions.

According to Adi Avidor, the graphing calculator supports a variety of functions. Specifically, trigonometric, exponential, logarithmic functions and all their compositions are included. The feature is available now in modern browsers.

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
