Consider the system modeled by:

x' = Ax + Bu , y = Cx + Du

-5 1 -1
A = , B = , C=[1 0] , D=0
1 -5 1

a) Determine the transition matrix eAt using the eigenvalues and eigenvectors method

b) Find x(t) and y(t) if the input is a unit step function when x(0)=[3 -1]T

c) Determine the controller u(t) if x(0) = and

2e-21+ e-12
x(3) =
-2e-21+ e-12.

Real Life Applications of Complex or Imaginary Numbers

When solving a quadratic equation using the quadratic formula, it is possible for the b2 - 4ac term inside the square root (the discriminant) to be negative, thus forcing us to take the square root of a negative number. The solutions to the equation will then be complex numbers (i.e., involve the imaginary unit i).

In the real world, where might these so-called imaginary numbers be used?

When using a formula, we often know the value of one variable to a greater degree of accuracy than we know the others. I need help to understand, what affect, if any, does it make on our use of a formula if we know the value of one variable to a greater degree of accuracy than another? Please assist.
