Coefficient

Definition

In mathematics, a coefficient is a numerical value that is used to scale or multiply a variable in an equation. Coefficients are commonly used in algebra, calculus, and other mathematical fields to represent the relationship between variables in an equation.

For example, in the equation y = 2x + 3, the coefficient of x is 2, which means that for every unit increase in x, y will increase by 2 units. The coefficient of 3 is a constant term, which means that y will always have a constant offset of 3, regardless of the value of x.
