1. The problem statement, all variables and given/known data Define f:R--->R as follows: f(x)=x-[x] if [x] is even f(x)=x-[x+1] if [x] is odd Determine the points where f has a limit and justify 2. Relevant equations 3. The attempt at a solution I'm not even sure where to get started. I assume that f has a limit evrywhere except the integers, but not so sure. Maybe I should try each case seperately.
