Formlerne

Formlerne is a term used in Danish and Norwegian to denote a collection of standardized expressions: it translates to "the formulas." In Danish, Formlerne is the definite plural form of formel (formula); in Norwegian contexts, the corresponding definite plural is formlene. The term is common in educational materials and reference works to label a compiled list of essential formulas that students are expected to know.

In practice, Formlerne appears in textbooks, classroom handouts, and online resources as a concise reference for mathematical, geometric, physical, and chemical formulas. The contents typically include algebraic identities, geometric area and volume formulas, trigonometric relations, and basic equations of motion or thermodynamics, though the exact set varies by curriculum and country. The form is usually a short, self-contained entry for each formula, sometimes with variable definitions and units.

Linguistic and cultural notes: While the exact spelling and usage differ between Danish and Norwegian, the concept remains common across both languages as a convenient reference to standard formulas. The term is not a mathematical concept in itself but a label for a curated list used in teaching and problem solving.
