stuðul
Stuðull is the Icelandic term for coefficient, a number that multiplies a variable or term in a mathematical expression. In algebra, coefficients determine how much each term contributes to the value of the expression. For example, in the polynomial 3x^2 + 2x - 5, the coefficient of x^2 is 3, the coefficient of x is 2, and -5 is the constant term (the coefficient of x^0).
In equations and systems, coefficients appear as multipliers of variables. In a linear equation such as a
In statistics, a coefficient often refers to a regression coefficient, which quantifies the expected change in
The term is also used broadly in science and engineering to denote any multiplier or proportionality constant
Overall, stuðull is a foundational concept in mathematics and applied sciences, identifying how much each term
