Autumn 2007 pdf pdf In problem 1, the integration should be with respect to u and not t (in other words: replace the dt in the integral by du).
In the solution of problem 2b, the time dependent part should be e((1-(n/2)^2)t instead of e1-(n/2)^2 t.
In problem 4b, the approximation for u' '(0.1) is 4.545 and not 5.03 as claimed in the solutions.
