Win a Math Guide by being first to answer this challenge question correctly

It’s exciting times around PWN HQ—lots of things going on. 2014 should be a fun year for SAT prep. That has nothing to do with this contest, of course. I just like to open these contest posts with a little friendly chatter. I bet nobody even reads this stuff. :/ ANYWAY, here’s a challenge question! (more…)

A challenge question for the heck of it

I was just noodling around with Geometer’s Sketchpad today, you know—like a totally normal person, and I made this figure, which I thought would make an awesome challenge question. Wasn’t even planning to post a challenge question, and then BAM! Inspiration. In the figure above, equilateral triangle DEF is partially obscured by a semicircle with (more…)

Some updates, and a challenge question

Phew! It’s only been like three weeks since I last posted but in Internet time that’s forever. Sorry about that. I’ve got about two weeks left in my Master’s program, and I’ve been completely inundated by papers and presentations. My thesis is basically eating me alive. I seriously don’t know how I’m going to get (more…)

Challenge question: Functions are awesome

It’s been a while since I’ve posted a challenge question. There are two main reasons: my own schoolwork, and the fact that most of my PWN time in the past month or so was dedicated to the Essay Guide. Now that I’m done with that, it’s time to get back in the swing of things (more…)

Challenge – Let’s roll

My holiday book giveaway is still going strong until January 1, and you can still get your name in there to try to win the daily random drawing, but I figured it was high time for another challenge question. The first person to post a comment on this post with the correct answer will win (more…)

Weekend Challenge – By request

I quickly agreed, but it’s taken me longer than I wanted it to because I’ve been having a hard time hitting the right level of difficulty for a challenge question. I’m still not sure I’ve nailed it, (more…)

Challenge – The floor is lava

Someone on the Q&A page asked me to do one of these “point A to point B” questions, so I figured I’d try to come up with one worthy of being called a challenge question. I think this is a bit easier than the usual. I expect someone to get it pretty quickly. Please note: (more…)

Weekend Challenge – Epic playlist

Thanks to Hurricane Sandy, this has been a rough week for a lot of people. If you’re feeling charitable, please note that I am still giving away Math Guides for donations to the Red Cross. Let me note, before we get into this, that these challenge questions are WAY harder than anything you’d see on (more…)

Weekend Challenge – We haven’t done one of these in a while

Hey guys. Hope you’ve been well. I’ve been buried under mountains of work for grad school. It’s awesome. I’ve also been answering a ton of questions over at my Q&A site, which is really awesome, minus the sarcasm inherent in the previous usage of “awesome.” Anyway, I was thinking about you guys the other day, (more…)
