Expand the definitions of 
and 
. Then you get a proper expression for the ion-accoustic dispersion relation. To plot it in some dispresion-less fashion, have a think about what is the natural quantities to use for normalization? Speed of light? Proton mass? Fine structure constant? Plasma frequency? Boltzmann's konstant? Debye Length?
