  Figure 3: Pole-zero plot of a fourth-order system with two real and two complex conjugate poles. Solution: The system has four poles and no zeros. The two real poles correspond to decaying exponential terms C1e−3t and C2e−0.1t, and the complex conjugate pole pair introduce an oscillatory component Ae−t sin(2t+φ), so that the total ...

We will take a more detailed look of the 3 possible cases of the solutions thusly found: 1. (When b2 − 4 ac > 0) There are two distinct real roots r 1, r2. 2. (When b2 − 4 ac < 0) There are two complex ...

  complex values of the 6 roots are shown. Keep the modulus slider at 1 and set the angle to 0. Write down the value of each root and compute its argument (angle). Now move the angle of z to π/2 radians and write down the value of each root and compute its argument. Finally, use a calculator to show these values satisfy your answer to part (a).

  The square root of -1 has two values, +i and - i. While these two values are the negatives of each other, they are algebraically the same. The square root of -2 is expressed as 1.41421356237i which is an imaginary number and a particular case of complex numbers. The subject of complex numbers will be covered in a future installment of

  The expression is read as "root nine", "radical nine", or "the square root of nine". Numbers can be raised to powers other than just 2; you can cube things, raise them to the fourth power, raise them to the 100th power, and so forth. In the same way, you can take the cube root of a number, the fourth root, the 100th root, and so forth.
