Now, when users type in a function -- for example: sin(x) -- the first search result will be an interactive graph allowing users to explore different related values for x and y.
Users can also plot multiple functions by separating them with commas. The new feature is available in most browsers and "covers an extensive range of single variable functions including trigonometric, exponential, logarithmic and their compositions," writes Google engineer Adi Avidor.
"I hope students and math lovers around the world find this experience as magical as I found the graphing calculator so long ago," Avidor says.
Google' search bar has actually long been friendly to the mathematically inclined -- or challenged. The calculator feature, which has existed for several years, allows users to type in mathematical equations -- ranging from the simple to the complex -- for real-time answers.
Users can also find answers to worded problems with numerical answers, for example the number of seconds in a year. Other number-based reference tools include unit conversion, for example 75 centimeters in inches, and public data, for example the population of San Francisco.
