9th edition vs 8th edition:  You may use either edition, but if you choose to use the 8th, you should be 
aware of the following:
<P>
There are some changes to the text.  A very brief description of these modifications can be found at

<h1>  For 22M:100 HW 10</h1>

Note section 5.5 in 9th edition = section 5.6 in 8th edition.  Thus 
for 8th edition<BR>

 HW 10 (due 4/17)<BR>
5.6: 7 (you must provide complete answers including induction proof and 
determine radius of convergence.)<BR>
7.4: 1, 5<BR>
7.6: 4, 10<BR>



<hr>

<P>
There are very few changes with respect to the HW problems.  For those who use the 8th edition instead 
of the 9th, you should be aware that
<P>
Section 3.3 in the 8th edition has been deleted.  Hence <BR>
Section 3.4 in 8th = section 3.3 in 9th<BR>
Section 3.5 in 8th = section 3.4 in 9th,<BR>
Section 3.6 in 8th = section 3.5 in 9th, etc.
<P>  Section 5.4, 5.5 in 8th = section 5.4 in 9th<BR>
Thus in 8th edition do 5.5:  2, 3, 4, 7, 10 and 5.4: 8<BR>
<P>
Section 6.3 has 6 new HW problems. <BR>
<P>If you plan to do extra credit problems from 6.3, e-mail me for 
conversion.<BR><P>


 Hence from the 8th ed, do
for Assignment 7 (due 10/22)   6.3: 5, 8, 9, 10, 13, 15, 
Also do problem 11 from 9th edition:  (a) Sketch the graph of the given function. (b) Express f(t) in terms of the unit step function 
u<sub>c</sub>(t)  where for problem 11:  f(t) = t 
for 0 &#8804; t <  1; 
t-1  for 1 &#8804; t <  2; 
 t-2 for 2 &#8804; t <  3; 
0 for t 	&#8805; 3.

<P>For Assignment 8:  6.3:  24, 25, 28, 29<BR>


<P>
Section 7.3 has 1 new HW problem.  Hence from the 8th ed, do
   7.3: 14, 15, 16 
<P>
Note I may make minor changes to the above.  Also if there are errors in my 8th to 9th edition 
conversion, please let me know.
