Differentiation is a general term used across disciplines to describe the process of distinguishing or making something different. The exact meaning depends on the field, but the core idea is establishing or recognizing differences.

In mathematics, differentiation is the operation that computes a derivative. The derivative of a function measures how the function’s output changes as its input changes. It is denoted f'(x) or df/dx and, geometrically, represents the slope of the tangent line to the graph at a point. Differentiation follows rules such as the sum, product, quotient, and chain rules, and it underpins much of calculus, physics, and engineering.

In biology, differentiation refers to the process by which unspecialized cells become specialized cell types, enabling the development of tissues and organs. This cellular differentiation is guided by regulatory genes and signaling pathways and is essential for growth, development, and tissue maintenance.

In economics and business, differentiation describes strategies used to make products or services distinct from competitors, often by emphasizing unique features, quality, or branding. In education, differentiated instruction tailors content, processes, and assessments to accommodate students’ readiness, interests, and learning profiles.

Across these contexts, differentiation centers on creating or identifying differences to achieve specific outcomes, such as understanding change, guiding development, or gaining a competitive edge. The concept derives from the Latin differentia, meaning “difference.”
