5.55 Be sure to use different order Pad/'e approximations to
ensure the accuracy of your determination of K for stability.
5.47 (a) - (d)
The following are short answer or True/False questions
Give the condition from which the root loci are constructed.
Determine the points on the root locui at which K=0 with
reference to the poles and zeros of G(s).
True or False: The asymptotes of the root loci refer to the angles of the root loci
when K approaches infinity.
True or False: There is only one intersection of the asymptotes of the root locus.
True or False: Adding a negative pole to G(s) has the general effect of pushing the
root locus to the right; whereas, adding a negative zero pushes the locus to the left.
