What is the difference between \oint and

\int ? Where is \oint used ?

Answered by dioph last updated on 21/Aug/17

\oint indicates the integral is calculated

in closed path . For instance, for

a conservative field A, \oint A d s = 0 .

Works for any n - dimensional

closed surface as well . {Gauss}^{'} law

for electrostatics states that

\oint D dS = Q, which means that

the integral of the electric field density

through any closed surface equals

the charge encapsulated by the same

surface . Hope that helps
