For this problem, we define the   fractional part of x∈R_(≥0)  as  {x} = x − ⌊x⌋  where ⌊x⌋ is the integer part of x, i.e  the greatest integer less than or equal  to x.  (a) Draw the function {x} in a cordinate  system for 0≤x≤3  (b) Find the area A_n  , under the graph  of {x} between 0 and n∈N as given by  A_n =∫_0 ^n {x}dx.      M.m

the graph of y={x} is following.  we can see that  ∫_0 ^n {x}dx=n×(1/2)=(n/2).
