|Spring 2006|| There is an error in problem 2a:
The function f is equal to 1 for pi/2 < x < pi, not for pi/2 < x < 1.
|Autumn 2007|| 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.
|Spring 2011||In problem 4b, the ODE should have been y''-6y'+9y=0.|
|Autumn 2014|| There is an error in problem 5a:
The interpolation points xi should be -2,-1,0,1,2 instead of -2,1,0,1,2.
|August 2017||In the solution of problem 2b), the sign of k in equation (1) and (2) should be the opposite for the rest of the solution to make sense. In the solution of problem 5, the y_2 should use 0.995, and not 1 in their computation.|
