Website: graph.tk<\/a>.<\/em><\/p>\n

It does nothing more and nothing less than you’d expect it to. Simply put, it graphs functions of all different kinds!<\/p>\n

The interface is beautiful not because it has a thousand buttons, but because it is so simple and straight to the point. Here’s what you see when you load up the website:<\/p>\n

\"\"<\/a>
In case you're wondering what that function in the right hand top corner is, it's a derivative.<\/figcaption><\/figure>\n

You can add almost an infinite number of functions, and toggle their display via the colored checkboxes. And this isn’t your ordinary Cartesian coordinate grapher; it can even handle polar functions<\/a> and inequalities! The controls are very intuitive: use your scroll wheel to zoom in and out, and left-click + drag to pan around. There’s even a screenshot option built-in to the page so that you can take a picture of your beautiful graph! The equations are displayed as you would expect to find them in a mathematics textbook (with LaTeX<\/a>), and for you tech geeks, it’s built with HTML5<\/a> and it’s open source<\/a>.<\/p>\n

The only caveats to this otherwise awesome web app are that you can’t find points of intersection<\/a> or roots of a function<\/a> so easily… but that’s where your high school\/college algebra skills come in!<\/p>\n

I would give this app an overall rating of 9\/10 (10\/10 if only it had tools to find intersections\/roots), and I highly recommend it to anyone who needs a quick graphing calculator because they’re too lazy to go downstairs and get their backpack.<\/p>\n
