Integrate f(x,y) = x2y2 along line y = x,
0 ≤ x ≤ √2
Key steps are to parameterize path, rewrite integral in terms of
parametric definitions of variables, multiply integrand by magnitude
of derivative of path vector
How about y/x along curve c1(t) = 〈t,t2〉, 0
≤ t ≤ 1/2, followed by c2(t) = 〈t, 1/2t〉,
1/2 ≤ t ≤ 1?
