三角関数弧度法即答ゲーム for PC

This is an app to practice trigonometric functions learned in High School Mathematics II.
Although it was created to be used in math classes, it can also be used for home learning.

First, let's practice in "radians from diagram" mode so that you can guess the number of radians from the unit circle.
Next, practice finding the values ​​of sin, cos, and tan quickly and accurately in "Trigonometric Values" mode!

If you have any problems or improvements, please feel free to contact us.
However, please note that since I am a beginner in app development, I cannot implement difficult functions.

This app is a completely free app that does not use advertisements in the main game.
Since the development costs are self-financed, we would be happy if you could support us by watching advertisements or making payments using the button at the top left of the app.
However, cheering will not change the game content.
You will accumulate "support points", so it will be encouraging if you share your screenshots on SNS etc.

This app is used as a teaching material at school, so no BGM or sound effects are used in the main game.
However, please be careful as there may be sound when displaying advertisements.

If you would like to introduce it at your school as part of the GIGA School Initiative, the developer will be happy if you let us know via the inquiry form.
