Assignment:
Sketch the root locus for the following closed loop system as α varies from -∞ to +∞. You should calculate all steps and show the positive and negative gain loci. It is recommended that you first find the positive locus and then sketch the negative ∞ locus.
(Real axis solutions of b x da/ds - a x db/ds = 0 are s = + 1.061 and s = +3.605.)

Provide complete and step by step solution for the question and show calculations and use formulas.
