Learning outcomes

On successful completion of the course, students will have acquired the basic knowledge of one-variable calculus, vector calculus and linear algebra, the first elements of multivariable calculus, complex numbers and the most elementary methods for solving ordinary differential equations. In particular, students will be able to represent data or functions in graphical form, to apply one-variable and multivariable calculus and to perform operations on vectors and matrices and will know how to use some basic concepts of scientific computing, such as error analysis, approximation of experimental data, interpolation, numerical integration, nonlinear equations and systems of linear equations.

Teaching methods

Lessons accompanied by exercise classes with tutor.

Assessment methods

The course assessment consists of a 3 hour open book examination (5 exercises on the topics covered in the course) followed by an oral examination.
Each exercise of the written examination is graded on a 6-point scale, and the pass mark is 50%, that is, 15 points in total. The validity of the written exam is limited to one examination session. The oral exam aims to test knowledge acquisition and to discuss exercises. The final mark, on a 30-point scale, is based on both parts of the examination.

The examination is unique for both modules of the course.

Teaching tools

Alma Mathematica [https://almaorienta.unibo.it/AlmaMathematica] : an online math-bridge course which with its diagnostic tests offers students the possibility to complete the missing pieces and refresh the material necessary for a successful study of mathematics. This self-study course is complemented by a virtual tutorial where students can get instant help by skype, e-mail and telephone.
