    What is the difference between these symbols?

    _

    - symbol 1 (an equal sign)

    ~ symbol 2 (wavy line over top of a straight line)

    ¯

    ~

    ~ symbol 3 (one wavy line over another wavy line)

    They were in the LDC and I have never seen them before.

    The symbols you are referring to usually (in the world of electronics, specifically on DMM:s) mean the following:

    - pure DC

    ~ AC and DC

    -

    ~ pure AC

    Hope it helps.

    Thanks Mats,
    But I wasn't specific enough in my question. It relates more to physics than electronics. This formula is in the LDC.
    fb . . . . . . (a´Ql²-ha²) ^½
    —— = 1 ~ (—————)
    fm . . . . . . ( a´Ql²-1 )
    My qestion is what is the difference between:
    =,
    ~, and
    ~
    ~
