Unformatted text preview: by hand in the lecture notes. . >> syms b s >> ilaplace(s/((s+1)*(s^2+2*s+5))) ans = 1/4*exp(t)+1/4*exp(t)*cos(2*t)+1/2*exp(t)*sin(2*t) You can see that f(t) is not identical as the one we did in class, but using simple trig identities, we can make it look identical. That is not really a concern. What is useful is observing the plot of >> t1 = 0:.01:10; >> f = 1/4*exp(t1)+1/4*exp(t1).*cos(2*t1)+1/2*exp(t1).*sin(2*t1); >> plot(f) Here we see that the system returns to a relaxed state in about 6 seconds....
