and Michigan Undergraduate Mathematics Conference.
|Students excel in actuary program|
we are approaching the end of the academic year, we want to commend
some of our students pursuing a careers in actuarial science. The
professional growth in this career depends on passing national
actuarial exams that cover such topics as probability theory, financial
mathematics, stock markets and many more areas related to mathematics
and economics. Hope College Department of Mathematics offers courses
and independent study to prepare students for some of these exams.
This year we want to mention names of Paul Nelson, who already passed three actuarial exams and was offered a position in an actuarial company in Illinois, Tyler Valicevic who passed two exams and is planning on working in an actuarial company in Michigan after graduation and recent Hope graduate Tae Hyun Choi who passed two exams and was accepted to the graduate school in Statistics at the University of Waterloo. Congratulations and best wishes!

|Math in the News: Andrew Wiles to receive Abel Prize|
professor Andrew Wiles was recently
awarded the Abel
Prize “for his stunning proof of Fermat’s Last Theorem by way of
the modularity conjecture for semistable elliptic curves, opening a new
era in number theory.” The prize also comes with a check for 6,000,000
Norwegian Kroner or a bit over $700,000.
Fermat's Last Theorem states that there are no whole number solutions to the equation xn + yn = zn when n is greater than 2. Pierre de Fermat, a 17th century mathematician, claimed to have a proof but none was ever found.
According to a recent article in The Telegraph, Wiles said, "Fermat's equation was my passion from an early age, and solving it gave me an overwhelming sense of fulfillment." Wiles worked for years on the proof for years by himself while he was at the Princeton University and completed his proof in 1994.
The Abel Prize is sometimes called the "The Mathematicians' Nobel" and is named after Norwegian mathematician Niels Abel.
Solvers of the Fortnight
In our last POTF we gave the following problem:
The line y = mx, where m > 0, forms an acute angle with the x-axis, and the point P = (a,b) lies in the interior of the angle. A line through P intersects both the x-axis and the line y = mx to form a triangle.
What is the minimum area of this triangle? Express your answer in terms of m, a, and b.
Congratulations to Zac Geschwendt and Jesse Ickes, both of whom correctly solved the last Problem of the Fortnight.
of the Fortnight
A light bulb is located at the top of the pole in the figure. How tall must the pole be if the point (1.25, 0) is right on the edge of the illuminated region? (And yes, that is a blue semicircle of radius 1 centered at the origin in the drawing.)
Write your solution on a semicircular piece of paper and drop it in the Problem of the Fortnight slot outside Professor Mark Pearson's office (VWF 212) by 3:00 on Friday, April 22. As always, be sure to include your name and the name(s) of your math professor(s) -- e.g. Justin Thyme, Professor Ty M. Lee -- on your solution. Good luck and have fun!
