Contexto: «mathematics»
(noun) coefficients are numbers that multiply a variable in a mathematical expression. They help us understand how much the variable is being affected by that number. For example, in the expression '3x', 3 is the coefficient because it shows how much we multiply 'x'.
Ejemplo
In the equation 2x + 5, the coefficient of x is 2.
Ejemplo
In the term 5y, there is no coefficient for y when it stands alone.
Ejemplo
What is the coefficient in the expression 4a + 7?

(noun) coefficients can also refer to numbers used in scientific formulas to express relationships between different factors. They help us understand how one thing affects another. For example, in physics, the coefficient of friction tells us how slippery a surface is.
Ejemplo
The coefficient of friction for rubber on asphalt is usually high, meaning it has good grip.
Ejemplo
The coefficient of friction for ice is low, so it's slippery and hard to walk on.
Ejemplo
How does the coefficient of drag affect the speed of a car?
