## Nemeth #math

### Expected solvable difficulty

• nohint+: experienced solvers
• keywords+: most solvers

### Level design

Idea of this question came from Codeforce #1505F, the fifth question in the April Fools’ Day Contest 2021. 1505F has shown its equation in 2 different notations, Nemeth and UEB. However, writing long mathematical notations in 2 different notations was time consuming and would not help much on solving this problem. I then decided to only use Nemeth as it is the most common result coming out of the search results when searching for “braille math”.

The main question is taken from a once viral integral question used in a Chinese university for Wi-Fi password.

\int_{-2}^{2}\left(x^3\cos{x\over 2}+{1\over 2}\right)\sqrt{4-x^2}\ \text{d}x
