You Can Now Graph Using PhotoMath

Three years ago, I wrote a post about Photomath, a software capable of scanning and solving equations using phone cameras. I haven’t used the software in a while, and recently discovered that it also has added a capability of graphing functions. It can now graph polynomial functions, rational functions, and trigonometric functions, exponential functions, and logarithmic functions. Recent improvements also allows solving for exponential equations, derivative, integrals, and limits.

Shown below are some examples. I scanned handwritten equations of functions and graph them.

To use Photomath, just open it, click the Camera icon and point to then expression or equation.


To view the graph, click the red rectangle containing the equation at the bottom of the screen.

Aside from the graph, the output also shows some important information about the function such as its x and y intercepts, domain, minima/maxima.

I think Photomath is a very good software that can be used for learning mathematics. Students can use this app to verify answers and also to explore graphs. Photomath is a free app and is both available on Android and iOS.
