Test 1 - MATHEMATICAL AND NUMERICAL METHODS IN ENGINEERING - NUMERICAL PART Prof. P. Zunino Total duration of the exam 1h45min ! Ciao Chiara, quando invierai il modulo, il proprietario potrà vedere il tuo nome e l'indirizzo di posta elettronica. Part I Quiz Answer to the following questions: 1 The condition number of matrix A arising from finite difference discretization of the Poisson problem is given by: (1 punto) /u1D43E(/u1D434) /similar_equal /uni210E2 /u1D43E(/u1D434) /similar_equal/uni210E−2 /u1D43E(/u1D434)/similar_equal()∆/u1D461 /uni210E 2 /u1D43E(/u1D434)/similar_equal/uni210E−1 2 Which of the following is the Upwind scheme for a conservation law with convection given by β?
