=March 19, 2008= We began by working on Supercorrections. Here are the expectations for these Supercorrections. After working on the Supercorrections, we went over the normal distribution homework on p. 374 and then learned about solving systems of equations involving three variables.
 * 1) Next to your correct solution, **write down where the question originally came from**. For example, for question 1, it is from homework 8.2, number 3. When you do that, think about why you missed it the second time- had you forgotten how to do it, had you not had a chance to stop by or email about how to do it, did you make a careless error? Include that in your reflections above your solution.
 * 2) If there is more than one way to do a problem, **show multiple methods**. For example, on question 9a, you could square the 8 and square the i separately and then negate the answer, or you could write out -1 x 8i x 8i and then write -1 x 8 x 8 x i x i. If you are not sure how to do a problem a second way, just ask!
 * 3) If there was any possible way of checking your answer, be sure to do so on the Supercorrections. For example, with question 7a, to check your answer, raise it to the negative 3/4 power- is it 27?
 * 4) In your reflections on the problem, identify the key elements of the problem that are necessary to solve a similar problem in the future. This is your chance to really learn how to do this math- you __**will**__ see these concepts again, whether it is on a future test, final exam, or future math course.
