I What is the Math symbol for "corresponds with"

  1. Mar 10, 2016 #1
    I looked on the wiki math symbol page and couldnt find one, so Im thinking "corresponds" is wrong word. Is it supposed to be equals sign with hat on it?
    for example, "energy directly corresponds to wavenumber"
    thanks for any help

    The colon " : " is used to indicate a ratio.

    The proportionality sign, " ∝ " is used to indicate that there is a direct, but unspecified, variation between two variables.

    For example:

    x ∝ y → y = k ⋅ x, where k is called a constant of proportionality
