COURSE AIMS

The course has two objectives: to present several fundamental mathematical tools for dealing with economic-financial problems, and to help students to acquire a precise and essential language. The course will emphasize how to develop a view toward critically re-examining mathematical concepts which students will find in their academic pursuits, and how to stimulate the capacity to use mathematical methods, tools and models in a wide array of applications. The course will cover basic topics in linear algebra, differential and integral calculus, and optimization; taken together, these concepts will provide an effective tool for analysing economic and business phenomena.

TEACHING METHOD

Lectures (course and pre-course classes), assignments.

ASSESSMENT METHOD

Grading will be based on

a.an on-line preliminary test, concerning basic knowledge, essential to pass to the written exam and given in the computer labs. Students who have correctly answered 8 questions in the mathematical section of the admission Faculty test are exempted. Preliminary test and exemption expire at the beginning of the new academic year.

b.a written exam in which students will be required to answer open and multiple choices questions,

c.an oral exam for students having achieved a grade on the written test of 15/30, 16/30 or 17/30 and also in other cases as specified in Blackboard. The oral exam concerns all the programme of the course (definitions, theorems, properties and their applications).

For all students it is possible to take partialtests:preliminary test (see a. above),first partial testduring the class period andsecond partial testat the end. More detailed information on the partialtests will be available on Blackboard.

NOTES

Basic knowledge will be included in the preliminary test and thus attendance at the pre-course classes is highly recommended. More detailed information on the pre-course will be available on Blackboard. An on line pre-course TEOREMAisalso accessible to the address .
