Google adds graphing to search-based calculator

Google has added some impressive new functionality to the calculator built into its search engine: a full graphing calculator implementation, complete with multi-coloured output.

Despite the company's streamlining process, which has seen multiple projects - including the Google Labs incubator system - closed down in order to better focus on the core business of advertising, engineers at the company are still given time to work on projects they love.

Adi Avidor, Google engineer and maths fan, has announced that the Google calculator - the hidden engine that allows you to type "1+2" or "333 USD in GBP" into Google's search engine and receive a calculated answer along with your search results - now supports graphing.

"I still recall the day when my friend Yossi came to school and showed off his brand new graphing calculator," Avidor explains. "I was stunned by how easy it was to plot complicated functions - meanwhile, the rest of us were still drawing them by hand on graph paper.

"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. You can zoom in and out and pan across the plane to explore the function in more detail. You can also draw multiple functions by separating them with commas. This feature covers an extensive range of single variable functions including trigonometric, exponential, logarithmic and their compositions, and is available in modern browsers."

It's an impressive addition to Google's search offerings, but one that is something more of a toy than a tool. Nevertheless, those with a mathematical bent may want to head on over to the Google home page and give it a go.
