Section 5.5 HW 

For all the following problems: 

a) Find the fundamental matrix for the system,   

b) Use the matrix exponential,  

to find the solution,

Where:   for problems 1,

and       for problems 9, 13, 15

Find the general solutions for the following systems: 

                      Answer:  x1(t) = c1e-t + c2e3t, x2(t) = -c1e-t + c2e3t 

 

         Answer:  x1(t) = c1e5t + 7c2e5t+ 3c3e9t, x2(t) = 2c1e5t, x3(t) = 2c2e5t+ c3e9t


      
Answer:
  x1(t) = (c1 + c2t+ (1/2)c3t2)e-t, x2(t) = (2c2 + c3 + 2c3t)e-t, x3(t) = (c2+ c3t)e-t


Answer:  x1(t) = (3c1 + c3 - 3c3t)et, x2(t) = (-c1 + c3t)et, x3(t) = (c2+ c3t)et
