Proof of Heron's Formula  by kid named SkyeHello everyone, I just joined. I shared a web link with the host of the MathIsFun website, and he suggested I share with this forum. However, the forum won't accept links, so just Google "Taking Heron's Fortress" Full disclosure: Skye is my son, but I hope you agree it's still a cool thing to share (set YouTube to HD so you can read formulas). FYI, I'm the only teacher Skye has ever had, and my approach is pretty simple: We start with the best books – for us that was Lial for Algebra I & II, then Barnett for Trig, now Swokowski for calculus. Then we take our time, and always keep in mind there are two levels to learn: how to get the right answer, and what's happening "under the surface". We never drill  we only enjoy ourselves! #2 20121108 13:09:36

Re: Proof of Heron's Formula  by kid named SkyeHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20121108 17:05:40
