For this discussion, you need to solve a problem from one of the sections 9.1, 9.3, 9.4, and 9.5. You must state the problem, where you located the problem, and then show the steps(with an explanation for each step) for solving it. It can be a problem from the textbook or from another location (as long as it is not worked out for you at that location). Stating the complete problem, giving the exact location where you found the problem, and showing your steps (with an explanation for each step) for solving a problem from the text or another location is required to get credit for this discussion. If it is from a website, provide the link to the site. Please put the source and problem number in the discussion title if it comes from the book. For example, a problem in the book would be “Textbook problem, p. 457, number 61”. When a problem is solved, other students must pick a different problem to receive credit.
