The Desmos Calculator: 15,000 Chrome Store Users

On September 1st of this year, we wrote on this blog about passing 2,000 Chrome App store installs of our graphing calculator. Now, less than two months later, we’re adding that many new installs per day.

Thanks to a beautiful redesign of the Chrome store, it seems as though more and more users are finding, installing, and loving the Desmos Calculator. We’ve been receiving tons of great feedback from our users, which is helping guide our next round of upgrades. If you’re one of the new visitors to the Desmos website, send us a message at calculator@desmos.com and let us know what you already love and what you’d love to see.

Happy Halloween and happy calculating!

Graph of the Week: Tangentially Speaking

This graph of the week features some creative linking of equations and variables. Except when a=0, the blue line will always lie tangent to the green parabola, no matter how a and b change. Find the original here.

This Weeks Graph O The Week Was So Cool That I

This week’s Graph-O-The-Week was so cool that I had to make a video about it.

This is the sine function as you’ve never experienced it before - beautifully color coded and with slider bars for each of the parameters. Notice how the pink dot (h,k) shows you where the sine graph would normally have passed through the origin. Moving along the graph, you’ll see that the green and red lines on the maximums and minimums show you the boundaries.

In the grapher, the way to make a parameter “slider bar-able” is to just type something like “a = 10” or “h = 1.5” etc. The left side has to be a variable and the right side has to be a simple number (“a = ½” or “b = 2^2” won’t work). Once you define a variable like that, you can reference it in any other equation and everything will update as you move the slider.

This is a perfect example of sliders - change “a” (the amplitude of the sine graph) and watch the bounding lines move up and down along with the graph. So cool.

Whoever made and shared this - you get two awards: graph of the week, and all around person of the week.
