1. The problem statement, all variables and given/known data

2. Relevant equations
The question is related to Riemann Sums

3. The attempt at a solution
I can not understand the notation of the question.
Can someone explain the question to me.
Or solve the question, i will understand it myself.
Thanks

Which notation are you unfamiliar with? I'll just take a stab at it now and assume you haven't seen $\lfloor x \rfloor$ before; these brackets represent the "floor function" which rounds down to the nearest integer.

For example
$$\lfloor 1.2 \rfloor = 1$$
$$\lfloor 0.999 \rfloor = 0$$
$$\lfloor 4 \rfloor = 4$$
