In order to reduce the steady state error for step inputs, the speed controller is modified as gsc(s) = 100 + kisc/s. find the value of the integral gain, kisc, that results in a steady state error eramp(∞) = 2.5%

What is the number 321,000,000 in scientific notation? also what is the number? ?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
