Online Calculator – Super Cool – from Kevin Hoang

Kevin Hoang, a recent contributor from the sunny state of California, recently emailed me with a link to an amazing, and free, online calculator that allows you to really do some neat things. Primarily, it allows you to place generalized functions in and then have the calculator change the parameters of the equation.

So, a simple example would be to have a linear function dependent on m and b graphed and then have a slider or even a simulation that shows what happens when you change m and/or b. They have a bunch of pre-made demos there as well, including one for trig that I cannot wait to show my precalculus students.

Desmos

Anyhow, here’s the link:
