QUIZZES (25 %)

There will be quizzes given every week. These quizzes will almost always be take-home, weekend quizzes given out on class on Friday to be handed in in class on Monday. They will consist of relatively simple homework problems which you work on by yourself and will be a way in which you can assure yourself you are keeping up with the course. The quiz, hints (and solutions) to the quiz will be posted on the web.

There may also be in-class quizzes and BONUS quizzes. Solutions to the quiz are found by clicking on the Quiz #.

 Date Assigned Date Due Topic Hint

Group Quiz 2

 Mon 04.13.09 Mon 04.13.09 Matlab and Approximation Theory You will probably need to draw a picture of the two curves in order to see where all the points of intersection lie in the plane. There are four. How would you get Matlab to plot these curves?

Quiz 5

 Fri 03.20.09 Fri 03.13.09 Solving Nonlinear Systems of Equations Think about the difference between Jacobi's Method and Gauss-Seidel. You'll need the formula for the inverse of a 2x2 matrix [a b; c d] which is [d -b; -c a]*(1/(ad-bc))
