    Feynman Path Integral and Free Particle

    can someone show me how to calculate a simple path integral so i can see how they work? more specifically, can it be a problem that involves free particles, preferably a "classic" problem?

    I want to understand the concept/idea and be able to perform a simple example, so if you could explain little details a long the way that'd be helpful as well.


    Thanks guys!

    You must learn to parameterize your path.

    I could be wrong, but I think the OP'er is referring to Feynman path integrals in quantum mechanics rather than contour integrals in complex analysis or multivariable calculus. I found a reference for Feynman path integrals here, that might prove useful.

    Ah, failing to read the forum heading again. Whoops.

    There are hundreds of textbooks - no doubt many in the library of the institute you study at - that contain what you want. Eg. Amazon.com: Quantum Mechanics and Path Integrals (9780070206502): Richard P. Feynman, A. R. Hibbs: Books

    And Google is an ideal resource for you to research your question too.

    Such research should be attempted before asking other people to do it for you.
