I stumbled on an article on Techcrunch announcing a cool maths tool, moments ago!
Its an announcement I wished happened ten years ago, and one that makes me think Physics and Maths Majors in colleges and unis students today are lucky!
One of the killer features of the Desmos Whiteboard is an interactive calculator that graphs equations as you write them. (Founder Eli Luberoff was a double math and physics major at Yale). Desmos has now taken that and rewritten it as a standalone online graphing calculator. It instantly draws the equations as you update them, it’s free, browser-based, color-coded, and you can share any graph with a bitly link.
You will never have to buy a Texas Instruments calculator again (do they still make those?)
Desmos closed an $800,000 seed round the day before Disrupt NYC from Mitch Kapor, Learn Capital, and Kindler Capital.
