Dear experts, I have found Qn 2bi) there is a complete solution
available for this whole question but i really would like to know
how to find qn 2bii).
Please indicate with clear steps. Thank you
(b) An unstable fly-by-wire combat aircraft has the longitudinal characteristics equation as follow: $+5.58 s3 + 8.212 s2 + 2.946 s - 1.107 = 0 Analyse its stability using the Routh Criterion. (i) (6 marks) (ii) If we know two of the roots are: s = 0.22 and S = -3.5, apply the given condition to evaluate the other two roots. (7 marks) (iii) Plot all the roots (or poles) on a Root Locus Plot. (4 marks)
