Formulassuch

Formulassuch is a neologistic term used in German-language online discourse to describe the practice of locating, evaluating, and compiling mathematical or domain-specific formulas. The concept covers searching through textbooks, databases, and community repositories for relevant equations, identities, or conversion rules, and then validating their applicability to a given problem. It can involve cross-checking sources, adapting formulas to different variables or units, and organizing found formulas for reuse.

Etymology and usage sense. Formulassuch derives from the German words Formel (formula) and Suche (search). The term is sometimes used interchangeably with Formelsuche, though Formelsuche is the standard term for a general formula search, whereas Formulassuch emphasizes an active, methodical approach or workflow.

Scope and applications. In mathematics and the natural sciences, formulassuch may refer to locating a differential equation, a trigonometric identity, or a chemical formula that meets specific constraints, and then tailoring it for new contexts. In software, data science, or engineering, it can describe querying symbolic expression repositories or codebases to retrieve reusable formulas, often aided by metadata, tagging, or computer algebra systems. Proponents highlight the importance of source verification to ensure accuracy and provenance, given the variability of informal online resources.
