How would you DEFINE the line integral:
int_aroundc[P(x,y)dx + Q(x,y)dy]
What's that supposed to mean? Isn't it already defined as you have written it?
That what I thought but I think theres some definition with limits and zeta and stuff...
You would define such an integral by choosing a parameterization for the path. Then it reduces to a regular integral in terms of the parameter. I don't know what "zeta" has to do with it but all the limits are hidden in the definition of the regular integral.
Separate names with a comma.
