Mathematical symbols in engineering include Greek letters, units, operators, and common notations used in equations, reports, and drawings. They serve as symbols for constants, special functions, and variables representing certain quantities in scientific and engineering contexts.

In engineering, Greek letters are used as symbols for constants, special functions, and variables representing certain quantities. Uppercase Greek letters often denote constants, sets, or finite differences, while lowercase letters typically represent variables, functions, or infinitesimal quantities. Greek symbols like Alpha, Beta, and Delta are applied in structural engineering, electrical design, and architectural proportions.

Engineering drawing abbreviations and symbols are used to communicate and detail the characteristics of an engineering drawing. They help people working with drawings in the manufacture and inspection of parts and assemblies to read symbols, notes, dimensions, and manufacturing instructions accurately.
