Hey as per ususal our physics course has run ahead of our maths course and started using this type of integral[tex]\oint[/tex] for the equation for electric flux
[tex]\Phi=\oint D . dA[/tex]
Where[tex]\Phi[/tex] = Total electric flux through an area dA with electric flux density D
The Attempt at a Solution
My Problem is that I dont understand the difference between this itegral [tex]\oint[/tex] and this one [tex]\int[/tex]
Can some one point out this difference for me please?
