Lab 3 Exercises

1.) Do Problem 2.3 (not Exercise 2.3), parts a, b, and c only. You may do part a at home. In part c, determine the necessary for 0.1% accuracy at t = 60 rather than at t = 4.

2.) Type in PROGRAM plot_function and run it. Include a screendump in your lab manual. Do you understand what each line is doing?

3.) Do Problem 2.4, part a only. You will want to edit Program cool. Save it with a different name like coolplt. You will often have many versions of your programs. Note that you can reuse what you typed in for item 2 above. It is not necessary to retype everything.

4.) Type in PROGRAM Compare in Appendix 2A and run it. Are the results what you expect? If not, be sure to understand what is happening, describe it in your summary, and remember it for future programs.

Summary: Describe accuracy. What methods can be used to determine the accuracy for a particular problem. What affects the accuracy? How do we control it?
