 Not Due



Homework 5:  New Due Date for both written and Matlab graphics  part:    Thursday  October 16

Chapter 3:  Second order equations

Section 1 -  page 142:  3, 5, 7, 10,11, 13, 17, 19.


NOTE
: For problems 10,11,13,19, 30 and 31, write the equations as a first order system of ODEs. Then use `pplane6' from MATLAB to graph the phase diagram and to plot the solution. For the use of `pplane6' consult ODEs using MATLAB, chapter 7, pages 93 to 100.

New Due date: both written and Matlab graphics  part  due on Thursday October 16  


Homework 6:    Due: Wednesday October 22

Section 2.  page 151:   2, 3, 5, 8, 11, 13, 15, 17.

Section 4.  page 164 :   1-4, 7, 8, 11, 12, 15, 17, 19, 21, 27, 29, 39, 40.
For problems 17, 19, 21, write the equations as a first order system. Then use `pplane6' from MATLAB to graph the phase diagram and to plot the solution


Homework 8:  Due: Wednesday November 5

Section 5. page 172:   2, 5, 8, 11, 12, 15, 23, 25, 30, 38, 39.
For problems 11, 12 and 15 write the equations as a first order system. Then use `pplane5' from MATLAB to graph the phase diagram and to plot the solution.

Section 6. page 184:   7, 8, 9, 10, 11, 12, 17, 18.
NOTE: pplane6 will not work on problems 17 and 18, since we can not add a right hand side to the pplane6 format.
