"Mathpix" that solves handwritten mathematical expressions with explosive speed and just shows graphs and LaTeX codes just by shooting them on the camera

When drawing mathematical formulas correctly on documents and websites, it is necessary to use formulas specialized in formulasLaTeXMust be used. However, if the formula is long and complicated, inputting is also very troublesome. "Mathpix"Is a smartphone application that not only tells you the source code but also how to solve equations and graphs by converting mathematical formulas and handwritten mathematical expressions in reference books to LaTeX notation simply by displaying them on the camera. iOS version and Android version are provided for basic free.

This time I will try using the iOS version. Go to the App Store and tap Acquisition to install.


When you start up, Mathpix will ask for access to the camera, so tap OK.


Mathpix provides four different scan modes. First, tap "Solver" which will instantly find the answer of the formula you took and select it.


For example, solve the equation in question (1) in the following image with Mathpix.


I will shoot a problem with the Mathpix camera. Put the equation you want to solve in the white frame displayed in the center. You can change the size freely by dragging the four corners of the white frame.


When you put it in the white frame, tap on the screen as it can be anywhere. Then reading is done for about 1 to 2 seconds ... ...


Equations and solutions are displayed. In the part surrounded by the top red frame, LaTeX source code of the read formula is displayed and it can be used by copy & paste. Also, what is displayed in Input is the equations read in, and it is the solution displayed in Result.


Since it means that it can be recognized by handwriting, I prepared handwritten mathematical expressions like the image below. Next time I will draw a graph of this formula. First, tap the icon at the bottom of the camera to switch to the mode to read the graph.


Tap "Graph".


Tap the screen so that the handwritten formulas fit in the white frame in the same way.


Scan finishes in a moment. The handwritten formulas are definitely recognized and the graph is displayed.


I could recognize multi-line formulas properly. Moreover, graphing can also be done while color-coding by formula. If you write log without writing the bottomCommon logarithmAs I write lnNatural logarithmIt was automatically processed as.


Furthermore, in the LaTeX scan mode, it was possible to save the loaded formula as PDF · LaTeX editor text file · TeX source file.


In addition, it is a charged element which requires a charge of 240 yen separately for 50 times of scanning, but in Wolfram Solver mode it is a computational knowledge engineWolfram AlphaWe will show you the solution of the equation you entered while showing the procedure.


Wolfram Solver mode requires user registration. To register, first tap the icon in the upper right and select Setting.


Tap Signin in the Authorization column.


User registration is free, you can link your Google Account, Facebook account, Twitter account. I will try registration only by e-mail address this time. Tap "Sign in with email" at the bottom.


After entering your email address, name and password, tap "Next" on the keyboard. Registration is complete.


To switch the scan mode, tap the icon at the bottom of the camera screen.


Select "Wolfram Solver".


Just like in Solver mode, put the equation in the white frame and tap the screen.


When you load it, a confirmation screen of the input content is displayed. If there is no problem tap Confirm.


Then, he shows the solution method carefully showing the deformation and way of thinking of the equation. When you look at the solution, you can see that it is solving equations while doing proper classification, not power technique. In addition, it is possible to use Wolfram Solver mode if it is free only once.
