1) Sketch the root locus of the following characteristic equations: a. s3 +14s2 + 65s + 102 + ks2 - 10ks + 41k = 0 b. s²+2s+5 + ks + 6k = 0 c. s² 5s 6+ ks + 8k = 0 -

Using the coefficient test, what can be concluded from the following characteristic equation? Q(s) = s5 - 6s³+4s²+20 Briefly explain.

The subplot function in MATLAB/OCTAVE is used to O put a title for the plot. O put label (information) to an x-axis. O draw data in continuous format. O none of them. To enter data in a matrix form in MATLAB/OCTAVE, each row should be ended by O comma(,) O space O colon O semi colon() The output data of MATLAB/OCTAVE program is displayed in window. O edit O figure O command O Graphic
