Mathematical Analysis I A
Objectives
The main goal of this discipline is to introduce the students to the universe of rigorous thinking. We start by the natural numbers and, in rigorous and construtive way, introduce all main elements of mathematical analysis up to the concept of differentiability.

Teaching method
6hs per week, including theoretical classes and exercises.
Evaluation method
Presence in class of optional.
Students are evaluted by two tests (T1 and T2); it is required minimum grade of 7 in the second test.
If T2<7, then MF=min(9,(T1+T2)/2); otherwise MF=(T1+T2)/2.
The final grade consists in the rounding of MF to the nearest integer (n.5 is rounded to n+1).
For students that to not obtain approval in tests ("continuous evaluation") it is possible to do a final exam ("recurso").
