Beta distribution Bimodal? The Wikipedia site for Multimodal Distributions states "Important bimodal distributions include the arcsine distribution and the beta distribution". I thought the beta distribution is unimodal.

A Beta distribution need not be bimodal, but it absolutely can be. When the parameters both are less than $1$, then there is bimodality.
I would have phrased it more like "arcsine distribution (name given to Beta(1/2, 1/2)) and other beta distributions that have both parameters less than $1$".
