Iode Tips:  
1.  You can use Iode and matlab in any of the EWS labs. See www.ews.uiuc.edu for a listing. You can connect to the EWS labs remotely using ssh. You can also use Iode anywhere that has matlab and internet access - you may need to download Iode again from the webpage www.math.uiuc.edu/iode .
2.  When you go to use Iode again - first change directory to my_iode (or whatever directory name you used) by typing cd my_iode if using Unix or Linux.  Then start matlab.  Then type iode in matlab.

Notes:

a. For #24 and #25, please use the definition of linear independence on p. 149, not the Wronskian.
b. Some of these questions are more theoretical than what you’ve done in the past. Start early so you’ll have time to ask questions before Friday if needed.
