### 1/5 — Can’t input anything on the quiz

*2023-02-16*

This looked like just what I’m looking for…. Except it doesn’t work. When it’s giving me ?/? for the triangle, for example tanB =?/?  I can click on the box… but there is no way to input any values. I can only click on the checkmark box, for it to tell me it’s wrong. Disappointing.

### 1/5 — Wrong theory

*2021-11-12*

Sine is wrong in the app. Cos and Tan is right.

**Developer response:** Thank you! The bug is just fixed!
