**How do you know when to use the chain rule? Yahoo Answers**

14/06/2007Â Â· Best Answer: Here is an example of a question where you use the chain rule before using the product rule: f(x) = sin( x e^x ) Doing this step by step, denote prime, or " ' ", as the derivative, we get f'(x) = cos (x e^x) [ x e^x ]' Now, we take the derivative of x e^x. This involves using the product rule... Everytime you take a derivative of a function you technically are always using the "chain rule", avoiding confusing definitions you can think of the chain rule as such:

**Best 25+ Chain rule ideas on Pinterest Ap calculus**

The chain rule is a rule for differentiating compositions of functions. In the following discussion and solutions the derivative of a function h ( x ) will be denoted by or h '( x ) . Most problems are average.... Chain Rule First, we should discuss the concept of the composition of a function which actually means the function of another function. It is easier to discuss this concept in informal terms.

**Solved I Know I Have To Use Product Rule And Chain Rule**

Chain rule for conditional probability: $$ This format is particularly useful in situations when we know the conditional probability, but we are interested in the probability of the intersection. We can interpret this formula using a tree diagram such as the one shown in Figure 1.23. In this figure, we obtain the probability at each point by multiplying probabilities on the branches... Functions Rule or Function of a Function Rule.) If we observe carefully the answers we obtain when we use the chain rule, we can learn to recognise when a function has this form, and so discover how to integrate such functions.

**Chain Rule and Product Rule Differentiating Math Forum**

Using the behavior of the parts, can we figure out the behavior of the whole? Yes. Every part has a "point of view" about how much change it added. Combine every point of view to get the overall behavior. Each derivative rule is an example of merging various points of view. And why don't we analyze the entire system at once? For the same reason you don't eat a hamburger in one bite: small... In these two problems posted by Beth, we need to apply not only the chain rule, but also the product rule. If you still don't know about the product If you still don't know about the product rule, go inform yourself here: the product rule.

## How To Know When To Use The Chain Rule

### Since f(x) is a polynomial function, we know from previous pages that f'(x) exists. Naturally one may ask for an explicit formula for it. One tedious way to do this is to develop (1+x 2) 10 using the Binomial Formula and then take the derivative.

- Chain Rule First, we should discuss the concept of the composition of a function which actually means the function of another function. It is easier to discuss this concept in informal terms.
- One is to use the power rule, then the product rule, then the chain rule. First you redefine u / v as uv ^-1. Then you're going to differentiate; y` is the derivative of uv ^-1.
