Many letters of the Latin alphabet, both capital and small, are used in mathematics, science and engineering to denote by convention specific or abstracted constants, variables of a certain type, units, multipliers, physical entities. Certain letters, when combined with special formatting, take on special meaning. Below is an alphabetical list of the letters of the alphabet with some of their uses. The field in which the convention applies is mathematics unless otherwise noted. ==Aa== *A represents: * *the first corner of a triangle * *the digit "10" in hexadecimal and other positional numeral systems with a radix of 11 or greater * *the unit ampere for electric current * *the Area * *the Mass number of an element * *the Helmholtz free energy of a closed thermodynamic system of constant Pressure & Temperature * *a Vector potential, in Electromagnetics it can refer to the magnetic vector potential * *an Abelian group in abstract algebra *𝔸 () represents the algebraic numbers or affine space in Algebraic Geometry *a represents: * *the first side of a triangle (opposite corner A) * *the scale factor of the expanding universe in cosmology * *the acceleration in mechanics equations * *the ''x''-intercept of a line using the line equation * *the unit are for area (100 m²) * *the unit prefix atto (10−18) * *the first term in a sequence or series (e.g. ''S''''n'' = ''n''(''a''+l)/2) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Latin letters used in mathematics」の詳細全文を読む スポンサード リンク
