Teaching Methods
THE COURSE CONSISTS IN A TOTAL AMOUNT OF 90 HOURS WHICH ARE WORTH 9 CREDITS. IN PARTICULAR, TEACHING INCLUDES THEORETICAL LESSONS (56H), CLASSROOM EXERCISES (31 H) AND ACTIVITIES AT THE PERSONAL COMPUTER (3 H) TO PRESENT THE SOFTWARE AND TO MAKE EXERCISES AND DOUBLE-CHECKING RESULTS.
ATTENDANCE AT LECTURES IS STRONGLY RECCOMENDED.
Verification of learning
THE ASSESSMENT OF THE ACHIEVEMENT OF THE OBJECTIVES WILL BE DONE BY MEANS OF A WRITTEN TEST AND AN ORAL INTERVIEW. THE WRITTEN TEST CONSISTS OF SOME QUESTIONS TO BE ANSWERED IN THREE HOURS. TO PASS THE TEST, THE STUDENT HAS TO BE ABLE TO SOLVE COMPLEX INTEGRAL ON CURVES AND TO PROPERLY USE THE RESIDUE CALCULUS; TO COMPUTE LAURENT AND FOURIER SERIER; TO BE ABLE TO FIND FOURIER TRANSFORM OF A GIVEN FUNCTION AND TO SOLVE A DIFFERENTIAL EQUATION BY USING THE LAPLACE TRANSFORM AND cTO SOLVE A STANDARD PDE (ELLIPTIC, PARABOLIC OR HYPERBOLIC) BY USING THE METHOD OF SEPARATION OF VARIABLES
THE STUDENT IS ADMITTED TO ORAL INTERVIEWS IF 18/30 MARKS HAVE BEEN REACHED IN THE WRITTEN TEST. THE WRITTEN TEST CAN BE REPLACED BY MEANS OF TWO INTERMEDIATE TESTS, ONE DURING THE COURSE AND THE SENCOND RIGHT AFTER ITS END.
IN THE ORAL INTERVIEW TYPICALLY THE WRITTEN TEST IS DISCUSSED AND THE STUDENT IS REQUIRED TO PROVE THEOREMS. IT WILL BE EVALUATED THE DEGREE OF MATURITY ACQUIRED ON THE CONTENT, THE QUALITY OF ORAL EXPOSITION AND THE AUTONOMY OF JUDGMENT SHOWN.
KNOWLEDGE OF THE RESIDUAL THEORY AND THE CORRECT APPLICATION OF THE VARIOUS METHODS FOR COMPLEX AND REAL INTEGRALS, THE ABILITY TO DEFINE THE INTRODUCED TRANSFORMATIONS AND THE ABILITY TO INTERPRET STANDARD PDE SOLUTIONS IN LIMITED AND UNLIMITED SPACE DOMAINS IS ESSENTIAL TO ACHIEVE SUFFICIENT RESULTS.
THE STUDENT ACHIEVES THE LEVEL OF EXCELLENCE IF HE KNOWS HOW TO DEAL WITH UNUSUAL PROBLEMS THAT ARE NOT EXPLICITLY FACED DURING THE CLASS. IT IS POSSIBLE TO START THE ORAL EXAM BY MEANS OF SHORT PRESENTATION AIMED AT DEEPENING A SPECIFIC TOPIC, TREATED DURING THE COURSE.
