## appleduardo how can i derivate the next function? one year ago one year ago

1. appleduardo

$\frac{ 2x+4 }{ \sqrt{2x+4} }$

2. etemplin

do you know the quotient rule?

3. appleduardo

not at all :/

4. etemplin

take a look at this: http://en.wikipedia.org/wiki/Quotient_rule theres a simple formula for it do you know the chain rule?

5. wio

Hint: $\sqrt{2x+4} \cdot \sqrt{2x+4} = 2x+4$So$\frac{ 2x+4 }{ \sqrt{2x+4} } = \sqrt{2x+4}$

6. appleduardo

mm i did the process step by step,, then i got = $\frac{ 1 }{ \sqrt{2x+4} }$

7. etemplin

@wio, that was creative, i never would have thought to simplify like that

8. etemplin

im fairly sure thats right @appleduardo

9. appleduardo

so am i wrong? mm

10. etemplin

no

11. appleduardo

ooh right! i understood! :D then if derivate what wio typed, ill get the same result i got! right?

12. etemplin

yes

13. appleduardo

thank you so much! :D you guys helped me a lot! :D thanks again
