Question

Find DxY using the rules of derivatives:
y=(3x^2-2)(4x^2-8x+6).

Answer 1

This is a product, so what rule should we use to differentiate?

Answer 2

*using the rules for finding derivatives

Answer 3

Yes, we will use the rules of differentiation to find the derivative of y

Answer 4

And how would I do that?

Answer 5

Well, as I said earlier, this is a product; what rule of differentiation would be applicable to a product?

Answer 6

Here's a basic list of differentiation rules

Constant rule, co-efficient rule, addition rule, power rule, product rule, quotient rule, exponential rule, logarithm rule

Answer 7

Pick the rule which would best suit our need to differentiate a PRODUCT.

Answer 8

product rule?.

Answer 9

Are you asking me?

Answer 10

I thought you knew .-.

Answer 11

I mean, are you asking me or are you confident that we should use the product rule?

Answer 12

Pretty sure it's the product rule

Answer 13

Okay, in addition to the product rule, which other rules of differentiation will be needed here?

Answer 14

@Chlorophyll I think that will confuse him even more..?

Answer 15

Quotient rule.

Answer 16

Is this function in the form of a quotient?

Answer 17

You ask too many questions and aren't helping -.-

Answer 18

I'm just trying to help you get a basic understanding of the rules of differentiation; it seems to me that you don't have solid foundation.

Answer 19

@frankypoo We're triggering your thinking, so you can do it YOURSELF :)

Answer 20

Then teach me, no need to keep asking questions..

Answer 21

You use the product rule along with the difference rule.

Answer 22

It's a big equation :c

Answer 23

I'll try do it myself, if I can't I'll come back

Answer 24

I got it.

Answer 25

and what did you end up with frankypoo

Answer 26

Would you like we check it for you?

Answer 27

Dx[(3x^2-2)(4x^2-8x+6)]=48x^3-72x^2+20x+16.

Answer 28

double-checked. ;)

Answer 29

Perfectly correct =)

Answer 30

:)

Answer 31

I don't understand how you go that answer if you were wanting to use the quotient rule. I hope you didn't copy this off some website.

Answer 32

Ill post other questions in this thread if I have any problems I need help with

Answer 33

no ma'm, all by myself.

Answer 34

Did you use the product rule?

Answer 35

Product rule ;p

Answer 36

okay, well good job!

Answer 37

:D

Answer 38

@frankypoo We're all here wish to help you for long-term goal, not just single post :)

Answer 39

awe :')

Answer 40

check this for me: "Find the derivative of the following function by first expanding the expression. f(x)=(6x+1)(5x^2+8), I ended up with 90x^2+10x.

Answer 41

Don't post more than 1 question in 1 post. Open the new post for it!

Answer 42

But I only wanted to ask youu :l

Answer 43

It's much more benefits to learn from different persons :)
