hi everybody, this is my first post, hope you can help me
check this proof for Green's theorem for a particular case:
http://en.wikipedia.org/wiki/Green's_theorem
rigth after equation (3) you have to calculate the integral
\int_{C_1} L(x,y)\, dx = \int_a^b \Big\{L[x,g_1(x)]\Big\}\, dx
but this is an integral of a function calculated on a curve, so there should be also
norm( C1' ) = sqrt( 1^2 + g'(x)^2 )
wikipedia's proof is rigth, I checked it on a book, so where am I wrong?
big thanks to all those who will answer!
