Base Knowledge
Knowledge corresponding to the syllabus from 1st year Mathematics I and Mathematics II curricular units: elementary mathematics, matrix calculus, differential calculus and integral calculus.
Teaching Methodologies
Expository method will be used to explain theoretical subjects and to analyze and solved problems.
Theoretical subjects and application examples will be presented. Each chapter will begins with motivation examples and will ends with the analysis of application examples. Exercises will be analyzed, discussed and solved, using mathematical software (Geogebra and Matlab) and spreadsheet program (Excel). Emphasis will be placed on the critical analysis of the selection criteria for mathematical techniques and consequent results.
Each chapter will ends with application examples to Civil Engineering.
In Moodle, will be available all the necessary documents for this course unit: textbook, exercise book, forms,
math tables, educational videos and exams from past years.
