coefficients
Pronunciation: [ˌkoʊɪˈfɪʃənts]
Word
Context: “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'.
Example
In the equation 2x + 5, the coefficient of x is 2.
Example
In the term 5y, there is no coefficient for y when it stands alone.
Example
What is the coefficient in the expression 4a + 7?
Context: “science”
(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.
Example
The coefficient of friction for rubber on asphalt is usually high, meaning it has good grip.
Example
The coefficient of friction for ice is low, so it's slippery and hard to walk on.
Example
How does the coefficient of drag affect the speed of a car?
