Do you like solving problems like these? .
. .
- Jack and Jill (two mathematicians, of course) meet at a cafe, and
Jack brings
up his three girls. Jill asks him their ages. “Well”,
says
Jack, “the
product of their ages is 36.” “Don't be ridiculous, I can't
figure them out just from that!”
replies Jill. Jack looks around stealthily, and murmurs
“Yeah, sorry. The sum of their ages is the number of pies in
this
cafe.” Jill counts the pies carefully and says, “but I
still can't
determine their ages!” “Ohhhh, whoops. Okay. My oldest
daughter
plays
the
piano.” How old are Jack's kids?
- Does there exist a function f on the
xy-plane,
taking only
three values, such that for every pair of points p and q which are
exactly one unit apart, f(p) and
f(q) are not equal?
- Find the area of the region in the xy-plane bounded by
y={1+(tan(x))√2
}-1, y=0, x=0
and x=π/2.
. . . then you should come to the Putnam
Examination

What: The William Lowell Putnam Examination is a nationwide
competition in Mathematics at the level of freshman calculus. It
will be held this year on Saturday, December 3. We will also participate
in the Virginia Tech Regional Mathematics Contest on Saturday, October 22.
Practice sessions are currently planned for: Sept. 16, 23, 30; Oct.
7, 14, 21, 28; Nov. 4, 11, 18; and Dec. 2. Practice
problems will be posted here one week in advance of each session, except
for the organizational meeting.
Practice Problems: about a week before each meeting, a list of
problems to be discussed will be posted below.
