Once you gain a little expertise, I found a site on the internet with more script names, but I'm told that not all of them may work here: http://meta.wikimedia.org/wiki/Help:Formula . To see the code I input in the integral above, simply left-click on it and a box will pop up.
Okay, since we may choose any (valid) path between the points (1,0) and (5,3), we may as well pick a simple one and choose the line: which doesn't cross either y=x or y=-x on the interval between the two chosen points.
What this means is that we are going to convert the line integral to a simple single integral by plugging into the integrand. So
after some simplifying. You can do the y and dy for the second part of the integral.
Thus , where is the y part I didn't do above.
