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.
