# Overall objectives:

1 - Stimulate and develop thinking skills, rigor, deduction and abstraction. Provide the students with theoretical and practical knowledge of basic Mathematics to be used as fundamental mathematical toolsin the most advanced courses.
2 - Study the fundamentals of the theory of Mathematical Analysis to several real variables, with corresponding applications to real world problems appropriate to the various areas of knowledge.
3 - Mastering the generalization to space IR^n of the concepts of limit, continuity, differentiability and integrability introduced in the curricular unit of Calculus I.

# Assesssment methods and criteria:

Classification Type: Quantitativa (0-20)

Evaluation Methodology:
Oral and written presentation of the syllabus contents of the curricular unit. Discussion and resolution of exercises and application problems in small groups or individually. Realization of two tests (with weight of 50% each) to be solved individually during the normal season. In this way, the student can, during the semester, evaluate their performance and change strategies if necessary. In the resit period of exams, the student can perform only one of the tests or, alternatively, a complete exam corresponding to 100% of the final grade. The importance of this examination, in addition to the assessment objectives, focuses on the student's ability to relate different parts of the subject.
