Question

Is there an easy way to do this problem? http://i.imgur.com/ogMOp.png

Answer 1

Grrr... Is it consistent?
It's usually just the area of the figure times some number... If it's consistent.

Answer 2

What do you mean by consistent? It's a line integral problem...

Answer 3

F•T = F•dr = F(x(t), y(t)) • r'(t))
More forms of this... etc. etc.
Probably haven't gotten that far in class.

Answer 4

That seems like too much work...

Answer 5

You'll see where these other forms of that equation are much better in some situations.
