Define

a. Prove that f is integrable on [0, 1] .

b. Calculate

Before proceeding for the proof of the problem, we prove the theorem

Theorem: Let f is a bounded function defined on [a, b] and let S be the set of points of discontinuity of f on [a, b]. if S has or as the only one limit point, then

Proof:

Let M=supremum ...
