Exercise 1: First complete inverse Laplace Transform by hand, then use partial fraction expansion in MATLAB to define the function, and find inverse Laplace transform, compare the results. (1) F(s) = (2) F(s) = (3) F(s) = 3 s(s+28+5) 2 (s+3)(s+1) 32 s(s+12s+32) Exercise 2: Work on the functions in Exercise 1, use the symbolic tool in MATLAB to obtain the inverse Laplace for functions and graph both results F(s) and f(t), compare the results with Exercise 1.
