Free online Graphing calculator - directly on the Internet


When I went to high school, we spent a lot of time drawing the equation of the straight line and quadratic equations by hand. We did this for example to study how different terms in front of x affected the graph's appearance.


With Desmos you can now do this directly in the browser, ipad or in the mobile and it is free also. In addition, you can save your graphs if you register.


In the example I made, you can see a function x ^ 3 + x + 5 derived twice and how the first and second derivative graphs look.
