Quotient Rule

The quotient rule is a rule used in calculus to find the derivative of a quotient of two functions

The quotient rule is a rule used in calculus to find the derivative of a quotient of two functions. It is specifically used when you have a function that is expressed as the division of two other functions.

If you have a function f(x) = g(x) / h(x), where g(x) and h(x) are both functions of x, the derivative of f(x) can be found using the quotient rule.

The quotient rule states that the derivative of f(x) is equal to (h(x) * g'(x) – g(x) * h'(x)) / (h(x))^2.

To apply the quotient rule, follow these steps:

Step 1: Identify the numerator and denominator functions in the given function f(x).

Let’s assume that g(x) is the numerator function and h(x) is the denominator function.

Step 2: Differentiate the numerator function g(x) with respect to x to find g'(x), the derivative of g(x).

Step 3: Differentiate the denominator function h(x) with respect to x to find h'(x), the derivative of h(x).

Step 4: Plug the values of g(x), h(x), g'(x), and h'(x) into the quotient rule formula:

f'(x) = (h(x) * g'(x) – g(x) * h'(x)) / (h(x))^2

Step 5: Simplify the expression if possible.

Step 6: The resulting expression is the derivative of the given function f(x).

It’s important to note that when using the quotient rule, you need to be cautious with parentheses and pay close attention to the sign placements while differentiating the numerator and denominator functions.

Remember to always double-check your work and simplify the expression if possible to get an accurate and simplified result.

I hope this explanation helps you understand the quotient rule in calculus. If you have any further questions or need clarification on any step, please feel free to ask.
