When converting a summation of the form
[tex] \sum x_i y_i [/tex]
to integration, how do we know if it's
[tex] \int x dy[/tex]
or
[tex]\int y dx[/tex]
At first I thought they're equivalent but obviously that's only true for a linear function with no constant offset.
I kind of see integration as a better form of multiplication so I've always had trouble with the fact that multiplication is commutative but integration isn't. A little help?
