Unformatted text preview: Homework 2/8 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 11-21 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. 5. 28) 60 ft/sec 2 ...
