|Math Club News|
||Bring your friends, your games, and your
friends' games to the 2nd floor of Graves Hall on Saturday, November
14th at 7pm for Math Club Game Night! Math Club will also provide games
Dr. Cinzori reports the mathematical formula for fun, F, at game nights is F = MATh, where M is the number of math students in attendance, A is the person's anxiety level in the past two weeks, T is the time spent playing games with friends at game night, and h is Planck's constant (of course!). Cinzori points out that since A is large and h is small, they basically cancel each other, and fun at game nights is directly proportional to the number of people attending and the time spent playing games. The Math Club had a successful game night last Saturday and will be hosting another movie night soon. (Look for an announcement in the next edition of Off on a Tangent.)

Career Day at GVSU
in a career in statistics? If so, head on over to Statistics Career Day
that will be held at Grand Valley State University on Friday, November
20, 2015 in the Kirkhof Center on the Allendale Campus. The intended
audience includes high school and college students from West Michigan.
This event will provide students an opportunity to learn about the many career options available in statistics by meeting corporate representatives to discuss job opportunities and university faculty to discuss graduate study. The keynote speaker is David Morganstein, Vice-President and Director of Statistical Staff at Westat, Inc., and president of the American Statistical Association.
Registration is free unless you want a lunch provided for $5. For more information about the event and to register click here.
|Math in the News: How to show your work|
this isn't real math in the news, but it was too funny to pass
up. The picture on the left, of a student's response to a test
question, showed up on Reddit a couple of days ago. The question asked,
"Bobby has four dimes. Amy has 30 pennies. Which child has more money?"
A fairly easy question and the student answered Bobby. The second part of the question asks, "How do you know? Show your thinking." By looking at the drawing the student made for the answer, it looks like it was spot on. Though I do wonder why the face is so sad. Perhaps it's a picture of Amy.
Solvers of the Fortnight
|In our last problem of the
fortnight we said, let
P(x) be a monic polynomial of
degree 2015 (that is, a polynomial whose leading term is
x^(2015)). Suppose you know that P(n) = n for n = 1, 2, 3, 4,
..., 2015. Is it possible to determine P(2016)? If so, what
is it? If not, why not?
Congratulations to Aleah Hahn, Colton Bates, and Zac Geschwendt -- all of whom correctly determined P(2016) in the last Problem of the Fortnight.

As always, be sure to include your name and the name(s) of your math professors -- e.g. Gene Yuss, Professor Bryll Yant -- on your solution.
