Here are comments and solutions to (some of) the problems on the 2011 Math Prize for Girls contest that took place at MIT on September 17. I’m going to try to resolve the problems in a straightforward, lo-tech way. I might indicate … Continue reading →

Problem #16 This problem involves standard manipulations with power series. In this case, technical issues about convergence are not important, so you can manipulate the expressions much as though they were polynomials and use the fact that if two power … Continue reading →

The official solution to problem #11 doesn’t actually prove that the “snug” circle is largest possible; it just claims that it is “clear.” If it isn’t clear to you, you could proceed by showing that any circle contained inside the … Continue reading →

Problem #6 If you know the standard formula for the area of a trapezoid, then you’ll know that the missing piece of information needed to complete this problem is the height of the trapezoid. If you draw in the height … Continue reading →

Since the 2011 Math Prize for Girls competition is coming up next month, I thought I’d go over last year’s contest.  The problems can be found here.  Because solutions are provide there too, here, I will indicate what students can do … Continue reading →
