Quick notation question

  1. Jul 4, 2012 #1
    I came across this notation which I've never seen before, it looks a little like feynmann slash notation but I don't think this is the same (see attatchment)
    It's kind of like 'd slash'
    dE = 'd slash' Q + 'd slash' W

    Could anyone give me a helping hand? o:)

    It looks like you are reading about thermodynamics. The slash signifies that the changes in Q and W are not true differentials. Quoting the Wikipedia article on the First law of thermodynamics which uses a δ rather than the slashed d:
