It is required a good knowledge of the analysis of univariate fucntions. It is required to have taken the exam of Mathematics I.

Final Examination: 

Written and oral examination. The written examination is composed of two calculus exercises to be completed in two hours. Books may be used, but graphical pocket calculators are not admitted. The oral examination covers theoretical topics. Both parts equally contribute to the final grade.
