The right hand side (RHS) of an equation, inequality or other relation is its' right hand side, rather trivially. This abbreviation is frequently used in proofs, when we don't want to write out the entire equation again.

For example, in \cos( x + y ) = \cos x \cos y - \sin x \sin y the RHS would be \cos x \cos y - \sin x \sin y.
