Learning objectives
The course object is to supply the students with knowledge and understanding of sequences and series of functions, ordinary differential equations (ODE), implicit functions and multivariable integral calculus.
Give to them the competence to treat and apply these instruments.
Objects of the course are also : judgement independence, strong written and oral communication skills, learning ability, in accordance with the specific objects of the mathematics degree.
Prerequisites
Analisi matematica I e Analisi Matematica 2 1° modulo

Teaching methods
Academic method. The teaching consists in frontal lessons where both theoretical and applicable aspects are expounded. The exercises are developped with the collaboration of the students and are programmed in order to they can solve independently the problems arising from the theoretical lessons.
Assessment methods and criteria
The understanding check consists in a final written test and, if it will be positive, in an oral discussion. In both the tests the student has to demonstrate knowledge, comprehension and to be able to connect knowledge and comprehension about sequences and series of functions, implicit functions and multivariable integral calculus.
The written test consists in 3 open questions regarding the above arguments.
The highest mark for each question will be 10, the total amount of the written test will be 30.
The total amount of the oral test is 30.
The marks will be attributed considering : the accuracy of the exposition and the operating methods.
The test will be considered sufficient if the average of the total amount of the written and oral tests is greater or equal to 18.
