What is this integral?

  1. Oct 4, 2014 #1
    Hello,

    I study right now my second physics matrial in university

    Wich discuss electricity and magnetism. The problem that it mostly use integrals to find the answers. In the book there was an integral that I didnt learn before. An integral with a small circle in the middle.

    Can some one define it for me? What is the difference between it and the usual integral.

    Thank you.

    Do you mean [tex]\oint f(t)dt[/tex]? That indicates a path integral around a closed path.
