Here's the centroid formula. Don't forget it!

have you seen this thread? >>>/aco/1122168

it is quite interesting

gross

hmm ok what can i use it for

Suppose you have a triangle with vertices at (x1, y1), (x2, y2), and (x3, y3), and you think to yourself "Gosh, I wish I could cut this triangle out of paper and balance it on the head of a needle, or hang it from the ceiling and have it balance flat". For these things, you need to find the center of gravity. The centroid is what that point would be if you found it dying after a violent accident and rebuilt it with titanium and steel, turning it into a thing half machine, half center of gravity, then gave it its own TV show.

Why is this written with three variables instead of x1, x2,... , xn

Probably because they haven't gotten to integration yet.

Calculus and calculus based physics is a hard game to play!
I want to be good at math again!
