In mathematics, a coefficient refers to a numerical value that appears alongside a variable or term in an equation or expression. It represents the sale or proportion by which the variable is multiplied or affects the overall equation.
For example, in the equation 2x+3y=7, the coefficients of x and y are 2 and 3, respectively. Coefficients help us understand how different variables contribute to the equation and determine the relationship between them. They are fundamental in algebra, calculus, and other branches of calculus, mathematics for solving equations, analyzing functions, and performing mathematical operations.
