coefficient
Prononciation : [koʊˈɛfɪʃənt]
Mot
Contexte : « mathematics »
(noun) a coefficient is a number used to multiply a variable in an equation. It tells us how many times to use that variable. If we have 3x, the number 3 is the coefficient, and it means we have three times the value of x.
Exemple
In the equation 4x + 2y = 10, the number 4 is the coefficient of x.
Exemple
In the expression x^2, there is no visible coefficient in front of the x.
Exemple
What is the coefficient of y in the equation 5x + 7y = 14?

(noun) a coefficient can also describe a numerical value that expresses a relationship between different quantities, like how much something increases or decreases. For example, the coefficient of friction shows how easily two surfaces slide against each other.
Exemple
The coefficient of friction between rubber and concrete allows cars to grip the road well.
Exemple
If the coefficient of friction is very low, it means the surfaces slide easily without grip.
Exemple
How does the coefficient of friction affect the performance of a vehicle?
