hwk13.1 - due tues 4/30

webwork13 #1-15
(as of W, I expect that you can do #1-11, but #12-15 will use a little more machinery which is presented in section 5.4 and we will cover on Friday)

I said in class that I would ask you to do 5.1#23.  You should look at this as you prep for the final, but I have decided not to assign it as homework.
