Simplify derivative after using product and chain rule

In summary, the student attempted to simplify the derivative using the Chain Rule and Power Rule, but was not able to arrive at the correct solution. They believe they may have made a mistake with a minus sign and are seeking further assistance.

The Attempt at a Solution



(x[itex]^{3}[/itex]+2x-6)[itex]^{6}[/itex][(x[itex]^{3}[/itex]+2x-6)(2x+x[itex]^{-2}[/itex])+7(3x[itex]^{2}[/itex]+2)(x[itex]^{2}[/itex]-x[itex]^{-1}[/itex]+1)]

This is the farthest I've gotten but when I do additional computation I do not arrive at the correct simplified solution.

edit- should be "simplify derivative after using power rule and chain rule"

hi biochem850! :wink:

looks ok so far :smile:

you've probably made a mistake with a minus somewhere later …

check them first …

if that doesn't help, then show us what you did​
 

Related to Simplify derivative after using product and chain rule

1. How do you simplify a derivative after using the product and chain rule?

To simplify a derivative after using the product and chain rule, you will need to use the product rule and chain rule to find the derivative of the function. Then, you can combine like terms and simplify the resulting expression to make it easier to understand.

2. What is the product rule and how is it used in finding derivatives?

The product rule is a formula used to find the derivative of a product of two functions. It states that the derivative of the product of two functions is equal to the first function times the derivative of the second function, plus the second function times the derivative of the first function.

3. How does the chain rule work in finding derivatives?

The chain rule is a formula used to find the derivative of a composition of two or more functions. It states that the derivative of a composition of functions is equal to the derivative of the outer function evaluated at the inner function, multiplied by the derivative of the inner function.

4. Can the product and chain rule be used together to find derivatives?

Yes, the product and chain rule can be used together to find the derivative of a function that involves both products and compositions of functions. The product rule is applied first, followed by the chain rule on the resulting expression.

5. Are there any tips for simplifying derivatives after using the product and chain rule?

One tip for simplifying derivatives after using the product and chain rule is to carefully distribute and combine like terms. It can also be helpful to factor out common factors and use algebraic simplification techniques. Additionally, it may be useful to double check your work and simplify further if possible.
