√(x²+y²)=5-z+f(z)-√(5z)
where f the floor function, that is, f(z) is z rounded down to the nearest integer.
- What is this the equation for?

Every week a new challenging problem about Bengt and his friends.
How to use
Many of these problems are quite difficult. Most of them require some knowledge of maths or physics to solve, and some you might not be able to solve anyway. But if you are like me, you can enjoy a good problem even without solving it.
For now, I have disabled comments, so as not to spoil the fun by showing any solutions. I will probably put up a page later to give credit to those who have solved any of the problems, and perhaps show the solutions too. If you have solutions, partial solutions, questions, or any other type of comments, send me an email: niklas.zechner{at}gmail.com
