Update on Assignment 2

Due to the update of the lecture notes (here again), Exercises 3.2 and 3.4 of the old notes are now Exercises 3.3 and 3.5 of the new notes.

This is due to the new Exercise 3.2 about divided differences at uniform points (which is needed to complete Exercise 1.10 about Bernstein polynomials, of Assignment 1).
