Hi guys. Would someone please explain to me what a cyclic integral is. I have seen them everywhere (especially in my Thermodynamics lectures) but my calculus book (1st year Uni) does not explain what they are and a search on googol has only led me to complicated examples. What I need is a layman definition (if it is possible) and if possible some sort of easy example that I can apply it to. Thanks heaps if anyone can give me a hand.
