Week 2  topics

1. Section .4 #8  ( similar to #13 in the text exercises)

The webassign I think has the inequalities messed up a bit; the -pi/2 should not be included but 0 can be included.  tan(-pi/2) is undefined so I think it should not be a less than or equal to sign after it.

2. In the text exercises for 1.1, #20, states to find C to make H(x) continuous at x=1 but in the definition of the piece-wise graph it has x=5 and x not equally 5    I think these should be 1.

3. Just a “heads up” about the 1.1 webassign homework.  It is long since 1.1 is an overview of the whole chapter.  I think it should be DUE after they’ve done all of chapter 1 since in the following sections we go into more depth on each subjects, limit theorems(1.2) , continuity(1.3) , tangent lines and the instantaneous velocity(1.4)
