Homework Statement
Evaluate the Work Integral,
## I = \int_\Gamma [ (\frac{y} {x^2 + y^2} + 1) dx - \frac{x} {x^2+y^2}dy]##
between the points (5, 30/pi) and (2,8/pi), using the potential function. Pesent your answer in exact form.
Homework Equations
##W = \int F . dr##
##\int_\Gamma (Pdx+Qdy)##
The Attempt at a Solution
Usually, we are given the curve along the line. This question we have not.
(5 - 2) and (30/pi - 8/pi) is the region between the points is it not?
Or do I rearange the given formula I, for y?
Do we even use the line integral formula, or use Green's Theorem instead?Thanks in advance.
