1. Refer to your text, Section 2.7, Problem 1.
(a) Use the graph to ﬁnd the secant slope on each of the following intervals:
i.
ii.
iii.
iv.
v.
vi. [−0.6, 0]
[−0.4, 0]
[−0.2, 0]
[0, 0.2]
[0, 0.4]
[0, 0.6] (b) Make a table of your secant slopes and use it to guess the tangent slope at the point P1 .
2. Refer to your text, Section 2.7, Problem 2.
(a) Choose three points on each side of P1 . For each choice compute the secant slope between
your point and P1 .
(b) Make a table of of your secant slopes and guess the tangent slope at P1 .
3. Repeat Problem 2 for P2 .
4. Section 2.7, Problems 1121 odd, ﬁnd tangent slope at the indicated location.
5. Section 2.7, Problems 27, 28 and 29. 1 Hints and Answers
1. You can’t read the graph with more than one decimal place of accuracy, so you shouldn’t try
for more than one decimal place in slopes. I got:
free end
slope −0.6 −0.4
1.2
1.0 −0.2
1.0 0.2 0.4 0.6
1.0 1.0 1.2 2. Depends heavily on your choice of points. The graph is hard to read, and the accuracy is
probably not even one decimal point. I got tangent slope −4.
3. Tangent slope 0.
