What math process is indicated by a symbol of an integral with a circle drawn at near the center of the integral symbol?
I believe that this is has something to do with physics, possibly calculations pertaining to WORK. I know what an integral is but I am not sure what this is telling me to do. Derive an integral in some fashion other than standard? As I said above the symbol is a standard integral symbol from calculus except there is a circle at the center of the symbol.
