That's ok up until you integrated 1 over the triangle and got 1/2. The area of a triangle with side length 1 isn't 1/2, is it?Just to clarify:
So you're saying that we don't even need the integral because you can pull the 4 out and if you just integrate (1), you get 1/2?
Then I multiply by 12 so the answer is 4*12*(1/2)=24?
jjheat deleted half the thread. That's not considered very polite or sporting. If everyone did it, it would make searching the old archives pretty useless. Feel free to start your own thread. The idea is to use Green's theorem to convert the hard contour integral into an easy surface integral. Try that.I have the same problem but I cannot see the entire thread
