So the question writing contest I proposed a few weeks back didn’t exactly explode onto the scene like I thought it would, but I still think it’s a fantastic way for you to improve your skills, so just FYI: it’s still open.
I got the question above in an email the other day. The writer prefers to remain anonymous, but I’ve given him Beta access to the Math Guide because it’s an awesome question. It incorporates circle properties, shaded regions, and has great, well-planned incorrect choices. That’s good hustle.
