Typo in the exam text (excercise 3, point b)

In exercise 3, point b, due to a typo in my LaTeX code the "^2" are missing. Therefore, in both the equation and the line under the equation all quantities have a square.

So:

- in the equation, \int_a^b f''(t) dt should be \int_a^b f''(t)^2 dt;

- in the first line under the equation it should be \int_a^b g''(t)^2 dt \leq \int_a^b \tilde{g}''(t)^2 dt
