# Quotient Rule Calculus Examples

Anything to make calculus easier right? Well then, let’s go! What Is The Quotient Rule. The quotient rule is a method for differentiating problems where one function is divided by another.. The premise is as follows: If two differentiable functions, f(x) and g(x), exist, then their quotient is also differentiable (i.e., the derivative of the quotient of these two functions also …

1. Naturally, the best way to understand how to use the quotient rule is to look at some examples. Notice that in each example below, the calculus step is much quicker than the algebra that follows. This is true for most questions where you apply the quotient rule. You will often need to simplify quite a bit to get the final answer.

The answer is that there's a trig identity that tells us that cos 2 x + sin 2 x = 1. So, d d x ( tan x) = cos 2 x + sin 2 x cos 2 x = 1 cos 2 x = sec 2 x as sec x = 1 cos x. So, we did it! Of course, it's quicker to just remember that the derivative of tan x is sec 2 x , but it's nice to know that you can still find it if you don't remember.

/ calculus / derivative / quotient rule. Quotient rule. The quotient rule is a formula that is used to find the derivative of the quotient of two functions. Given two differentiable functions, f(x) and g(x), where f'(x) and g'(x) are their respective derivatives, the quotient rule can be stated as . or using abbreviated notation: Examples. Use the quotient rule to find the following

The proof of the Quotient Rule is shown in the Proof of Various Derivative Formulas section of the Extras chapter. Let’s do a couple of examples of the product rule. Example 1 Differentiate each of the following functions. y = 3√x2(2x−x2) y = x 2 3 ( 2 x − x 2) f (x) = (6x3−x)(10−20x) f ( x) = ( 6 x 3 − x) ( 10 − 20 x)

By the Quotient Rule, if f (x) and g(x) are differentiable functions, then d dx f (x) g(x) = g(x)f (x)− f (x)g (x) [(x)]2. Integrating both sides of this equation, we get

Second, again, go back to the example and notice that, when simplifying, the first thing we do after taking the derivative is look for a common factor between the two terms in the numerator. In the example, we had a factor of x. We factored it out and canceled it with an x in the denominator. This happens quite often when using the quotient rule. 3. Third, the quotient rule itself is not …

The quotient rule is a formula that lets you calculate the derivative of quotients between functions. It is a more complicated formula than the product rule, and most calculus textbooks and teachers would ask you to memorize it. I don't think that's neccesary. So, I'll show you an alternative way of solving problems involving quotients that doesn't need the memorization of …
