What is the Difference Between \oint and \int in Electric Flux Integrals?

[rshalloo]

Homework Statement

Hey as per ususal our physics course has run ahead of our maths course and started using this type of integral$$\oint$$ for the equation for electric flux

Homework Equations

$$\Phi=\oint D . dA$$
Where$$\Phi$$ = Total electric flux through an area dA with electric flux density D

The Attempt at a Solution

My Problem is that I don't understand the difference between this itegral $$\oint$$ and this one $$\int$$

Can some one point out this difference for me please?

well i can't tel the difference you are asking but yes ... $$\oint$$ is called integral over whole area and $$\int$$ is just called integral ...

and both are integrated same way ...
