Going from proportional to equals

  1. Mar 18, 2014 #1
    Hi guys,

    This may well be a very trivial question but it isn't immediately obvious to me..

    I know if you have x is proportional to y by adding a constant you can say;

    x = cy

    However, if we have x is proportional to y + z, is there a similar 'trick' that can be used?

    Basically, i have an expression;

    J(w) [itex]\propto[/itex] [w-w0]^1/2 + [w0 - w]^1/2

    and want to set this equal.

    Thanks in advance!

    Ok great, so it is trivial. Thanks Arildno :)
