RHS

Rhs, usually written as RHS or Rhs, is an acronym with several meanings across different domains. In mathematics and related disciplines, RHS denotes the right-hand side of an equation or expression—the value or term that the left-hand side asserts to equal. In analysis and differential equations, the RHS may represent a forcing term or source function that drives the solution.

RHS also refers to the Royal Horticultural Society, a major UK charity devoted to gardening and horticulture. Founded in the 19th century as the Horticultural Society of London, it later received royal status and adopted the Royal Horticultural Society name. The RHS promotes gardening education and culture, organizes prominent events such as the Chelsea Flower Show, and maintains public and private gardens, including RHS Garden Wisley.

Additionally, RHS is commonly used in computing and programming to denote the value on the right-hand side of an assignment or expression (for example, in x = y + 5, y + 5 is the RHS). The acronym can therefore refer to several distinct concepts, depending on the context.
