22 Carefully read all of chapter 6 in the text. Then, do problems 6.4 and 6.5. Hand in the written out equations that you use, showing all work, your results, and the computer program, Mathematica, or Excel worksheet used.

23 Test covers chapters…1, 2, 3, and 6 of the textbook. You may prepare both sides of an 8 ½ by 11 inch sheet with equations, examples, notes, or anything else you may wish to have with you. You will need your calculator.
