course mth 163 I am having technical difficulty with links on your site. I cannot get to randomized problems in order to complete the 3 quizzes for assignment 8, also Texas instruments does not sell DERIVE anymore and the site where I found it does not offer a trial download. I hope to make it to the learning lab Monday (10th) or Tuesday(11th) to use DERIVE there for that assignment and maybe the links will be working by then. I will be moving on to assignment 9 until then. I have gone through the graphs and checked my answers to the solutions and I am comfortable with them. Thanks, Lorie
