The characteristic polynomial of a feedback control system, which is the denominator of the closed-loop transfer function, is given by s3 2s2 20K 7s 100K. Sketch the root locus for this system. [Section: 8.8]
CS 70 Discrete Mathematics and Probability Theory Fall 2015 Note 16 Random Variables: Distribution and Expectation Example: Coin Flips Recall our setup of a probabilistic experiment as a procedure of drawing a sample from a set of possible values, and assigning a probability for each possible outcome of the experiment. For example, if we toss a fair coin n times, then there are 2 possible outcomes, each of which is equally likely and has prob.bility 2n Now suppose we want to make a measurement in our experiment. For example, we can ask what is the number of heads in n coin tosses; call this n
