HW 57

Hi guys,

I think it'd be best to wait on the 4.2b WKS until we've done a few more
examples, so this weekend I actually want you to do the 4.2a WKS (emailed to you),
which will be more practice summation problems. If you've already started
the other one, don't fret, because that will be assigned for HW on Monday
and you'll be ahead.

HW 57

4.2a Summation WKS

Thanks and sorry to change things,

Mr. Joseph
