In mathematics and computer science the floor function is the function that takes as input a real number and gives as output the greatest integer less than or equal to denoted or similarly the ceiling function maps to the least integer greater than or equal to denoted or.
Homework statement integral x 2 x 2 dx limits are 0 to 2 i am using to represent the floor function.
In general the process you are going to want to take will go something like this.
The best strategy is to break up the interval of integration or summation into pieces on which the floor function is constant.

0 x.
The floor function turns continuous integration problems in to discrete problems meaning that while you are still looking for the area under a curve all of the curves become rectangles.
Floor x from 0 to 5 2 0 from 0 to 1 1 from 1 to 2 2 from 2 to 5 2.
Definite integrals and sums involving the floor function are quite common in problems and applications.
Homework equations the attempt at a solution of course normal integration gives x 2 2 x 2 2 which gives 0 for all cases so is it right to assume a floor function.
For example and while.
Rewrite the floor function as a piecewise function for every jump discontinuity and integrate each one separately.
