I thought it was a pretty simple ask but three other calculators failed me. The Desmos site keeps cool examples You may not have had much interest in math or graphing before, but a few moments on Desmos may change your opinion.

NextMultiple Expressions: Unlike many four-function calculators, all of your previous work remains visible on the screen.

The difference between the two blobs is the nature of their shapes. DO NOT USE THIS APP.

Combinatorics: Count combinations and permutations and calculate factorials.

Desmos is a graphing calculator on steroids Eli Luberhoff founded Desmos in 2011.

Any bugs in the system will still need to be worked out if there are any that is, but there are plans to move ahead with the technology and who knows, it may one day come out installed in new electronics.

NextThe developer wants Desmos to remain free to users It is the intention of Luberoff to keep Desmos free to anyone who wants to use it.

Now you can slide your slider or press the play button to watch an animation play out, if you have a graph connected to the variable. Designers are also finding it to be a tremendous tool for creating new designs for their businesses and new product lines. Some are very simple designs while others are actually novel and interesting.

NextAll of the work that you do on the site can be saved to your account.

You can use this program on Windows Vista and later. When you leave the site and return at a later time it will all be there just as you left it. And I would like to suggest a function for the mode of a set of data.

NextFor example, if you have two points, you can work out the gradient and y-intercept of the line formed by these two points, and then graph them..

If you add updates to the equation, you can watch it make the appropriate changes to the graph right before your eyes.

NextTables: Input and plot data, or create an input-output table for any function.

Watch this quick tutorial to learn how: Who knew piecewise notation could be so fun! Otherwise, the blob is a sort of ellipsoid shape that points in the direction of the function. You can make the blob more interesting by composing and summing additional sinusoids, but it slows down the blob due to greater computation time, which ruins the effect.

This is also an example of how technology is influencing our society and shaping the way that we learn.
