Exam | Problems | Solutions | Remarks |
---|---|---|---|
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 2006 | |||
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. |

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. |

Spring 2017 | In the solution of problem 8, p. 6, the matrix formula in the middle of the page, the vector (2,0,0) should be (4,0,0). The rest of the solution should be corrected accordingly. | ||
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. | ||
