Using Green's Theorem for Solving Line Integrals

[QUOTE="HallsofIvy, post: 4955395, member: 637751"] What you have shown is difficult to read! It appears that you meant that O and A are points: O= (0, 0) and A= (1, 2). But if so, then "over the point OA" makes no sense. I think you mean "over the [B]line[/B] OA". If [itex]y= 2x[/itex], what is dy? If [itex]y= 2x^2[/itex] what is dy? I'm not clear on what "3- the line OB, 4- the line BA" is supposed to mean when initially the you had the single problem, "From OB to BA", which also makes no sense since you do not go "from" one line to another. I think that what you mean is that all these integrals are from O to A, the third problem being [B]along[/B] the horizontal line from O to B, y= 0, and then along the vertical line from B to A, x= 1. If y= 0, what is dy? If x= 1, what is dx? [/QUOTE]
