MATLAB: Can anyone help me answer this question with matlab

inverse laplace

G(s)=K(s^2+6s+25)/(s(s+1)〖(s+5)(s+7)〗^2 )
Determine ?(?) by using inverse Laplace for ?=1 and ?(?)=?(?)

Best Answer

You need the symbolic toolbox for this
syms s t
K = 1;
U(s) = 1/s;
G(s) = K*(s^2+6*s+25)/(s*(s+1)*((s+5)*(s+7))^2);
C(s) = G*U;
c(t) = ilaplace(C)
Following is the output from symbolic toolbox
