:banghead) :banghead) :banghead) :banghead) :banghead) :banghead) :banghead) :banghead) :banghead) :banghead) this is what i feel like doing right now. i just struggled through the webassign and everything is so tough. I looked through my notes, which to me look like a foreign language, and i tried looking through the book to help me out, but even that offered little comfort to me. I know yelling at the computer screen wont help me any more on this webassign, but i do enjoy it. I made it all the way to 90%, and that seems to be the best that it's going to get.
A scout walks 6.5 km due east from camp, then turns left and walks 4.55 km along the arc of a circle centered at the campsite, and finally walks 3.25 km directly toward the camp.

This one caused me considerable trouble, and i know if i could understand my own notes i would be able to do that, but i cant. And the questions about wind and planes and the angle it needs to fly also gets me. I know Vab + Vbc = Vac or something along those lines, but again my rushed and skewed notes fail to deliver. I need me some help.
