Question

1) Find solutions to the following equa t ions having the specified initial value

 

  1. a) x" + 4x = 0 x(O) = 1 x(O)' = 0

 

  1. b) x" - 3x' + 2x = 0 x(l) = 0 x(l)' = - 1

 

 

 

2) Solve the following initial value problems

 a)

 

x' - - y                x(O) = 1 y(O) = 1

 

y' - X

 

b)

x' = y                         x(O) = 1 y(O) = 1

                   

y' = - x

 

 

3) Consider the system described by

 

x"' + 3x" + 2x' = u

 

Derive a state-space representation (i.e., x = Ax + Bu) of the system
