In the old days, you were pretty much limited to a handheld graphing calculator in order to produce graphs of equations. That has all changed in the past few years with the introduction of online graphing calculators. Unfortunately, not all graphing calculators are created equal. Furthermore, doing an Internet search for graphing calculators doesn’t yield as much as you would expect. I don’t believe there is any “best” online graphing calculator since it all depends on what you want to do with the calculator. 19 Great Online Graphing Calculators for Teachers and Students
