In calculus, the quotient rule is a formula used to find the derivative of a function that is expressed as the quotient of two other functions. It is derived from the basic rules of differentiation.

The quotient rule states that if you have a function y = f(x) which can be written as the ratio of two functions, say y = u(x)/v(x), then the derivative of y with respect to x can be calculated using the following formula:

(dy/dx) = (v(x)*(du/dx) – u(x)*(dv/dx))/(v(x))^2

In simpler terms, the quotient rule tells us that to find the derivative of a function that is expressed as a ratio, we need to differentiate each of the functions in the numerator and the denominator separately. Then, we multiply the denominator of the original function squared and subtract the product of the derivative of the numerator and the denominator from the product of the numerator and the derivative of the denominator.

By applying the quotient rule, we can find the instantaneous rate of change of a function that is given in the form of a quotient of two functions. It is a fundamental tool for solving a variety of problems in calculus, such as finding the slopes of curves, finding maximum and minimum points, and solving optimization problems.
