Open Book and Notes. Carefully explain your proceedures and answers. Calculators allowed, but answers mush be exact. The people in this quiz are Olympic Weightlifters.
(There will be women's Olympic weightlifting at Sydney, presumably Meiyuang Ding sill compeat -- She won the world championship at Athens this year.
Andrei Chererkin would like you to:
x + 2 y + 3 z + v + w = 1,
6 z - v + 2 w = 4,
-3 z + 2 v - w = 2
Note that there are infinitely may solutions. "y" and
"w" can be anything.
6 z - 2 v + 2 w = 4,
-3 z + v - w = -7,
z + v - w = 0
Naim Suleymanoglu woul d like you to , estimate the values of n needed to
obtain an acuracy of in numerically evaluating
by
Where M is a bound on the fourth derivative. Here M=1 will work.

Meiyuang Ding needs some matrixtrix calculations:
Write the sytem of equatiopns:
x + 2 y + 3 z + v + w = 1,
6 z - v + 2 w = 4
-3 z + 2 v - w = 2
In matrix notation as: Ax = b
A =
b =
Let B = , and C = . Find BC
