Remark: these are last year's solutions using the teaching model so your numerical answers can differ slightly.
CAVEAT: Exams of previous years are just given as an illustration of what a typical exam for this course looks like. However, note that the material covered in this class can change from year to year as well as the material included in the different exams. Keep in mind that the exams shown below are NOT necessarily representative of what you can expect this year.
CAVEAT II: The posted solutions are very extensive with the purpose of explaining the followed methods in detail. A typical exam solution submitted by the student can be briefer and still receive full credit.
