Have you used Google to calculate Mathematical Graphs? Google has recently added the Graphing functionality to it’s search feature. Now, you can quickly plot graphs just by making a Google search of your mathematical equations. The generated graphs will be colorful, accurate, neat and clean, you can even zoom, pan and read coordinates also. People are calling this feature as Google Graphing calculator, Google Graphic Calculator etc. Have a look at the below graphs generated using Google search: You can also generate shapes like hearts using Google graphs just like this: Google this for a Valentine’s day surprise: (sqrt(cos(x))*cos(200x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01, sqrt(9-x^2), -sqrt(9-x^2)

Get the heart-shaped Google graph like above just by clicking here. Google Graph for multiple mathematical functions

For generating graph for multiple functions, search in the functions separated with commas. You’ll get a separate line with different color for each function.

People generally use Graphing Calculators to plot and generate mathematical graphs quick and easy. But I guess, it has become easier than ever, you can do just by typing in your equation on Google, and you’ll see an interactive graph on the top of the search results page.

This functioning supports a wide range of mathematical functions such as trigonometry, logarithm, exponents, variables etc. But one thing you should remember, these graphs are available for functions with a single variable only (i.e. if you are using x, there is no scope of using y).

### Tips to Generate and Plot Graphs on Google

• Use ^ for exponentiation, eg. x2 should be written as x^2
• Use round braces for trigonometric angles and operation segregation eg. sin(x), tan(sin(x^2) , x/(x+log(x)) etc.
• Use rest of the operators eg. addition (+), subtraction(-), division(/),multiplication(*) etc normally.

It’s yet another simple feature from Google – those who work most on Mathematical graphs should definitely check it out. For me, it reminded me of my high school days when we used to plot Graphs manually using geometric compass, scales, pencils.
