coefficient
의미: A numerical or constant factor placed before a variable in an algebraic expression, or a multiplier measuring a particular property or characteristic.
In mathematics, a coefficient is the number that multiplies a variable, such as the 3 in 3x. In science and engineering, the term extends to describe measured ratios like the coefficient of friction or the coefficient of thermal expansion. It is a formal, technical word rarely used in everyday conversation outside academic or professional contexts.
