Prerequisites

Differential Calculus and Integral Calculus or similar skills

Assessment criteria, satisfactory (1-2)

Student is able to determine simple Laplace transforms with the aid of given formulas and calculator. He/she is able to solve simple applications that are similar to the model problems solved during the course. Student knows how to compute numerically coefficients for the Fourier series of periodical functions. Justification of solutions and using mathematical concepts may still be somewhat vague. Student takes care of his/her own studies and can cope with exercises with some help from the group.

Assessment criteria, good (3-4)

In addition, student is able to solve simple linear differential equations using Laplace transform and understands how Fourier series decomposes a periodic function to infinite series of waveforms with different frequencies. Student is also able to explain the methods of her/his solutions. Mathematical notations and concepts are mainly used correctly. Student is able to solve the given exercises independently and also helps other students in the group.

Assessment criteria, excellent (5)

In addition, student has an overall understanding of using course topics to solve various applications and the ability to present and justify the chosen methods of solution. Mathematical notations and concepts are used precisely. Student is motivated and also committed to help the group to manage the course.
