Question

can some one help me with six home work problems here so lost doing derivatives.

Answer 1

Thats what I am working on tonight, what's your problems? Also if you haven't checked it out Khan Academy.com has lots of great videos

Answer 2

the book wants me to differentiate the function g(t)=2t ^ -3/4

Answer 3

I tried solving this but my answer is way to far off from the book

Answer 4

Did you use the exponent rule?

Answer 5

yes i did, sorry my pc froze

Answer 6

f'=n(c)x^n-1

2(-3/4)t^-3/4-1

-1.5t^-7/4? that what you got?

Answer 7

yeah it's -3/4 t ^-7/4

Answer 8

sorry -3/2t ^ 7/4

Answer 9

Hey cool, your boosting my confidence here, LOL I got a test tomorrow night

Answer 10

I got time for one more before I get to get to bed, whats another?

Answer 11

A(s)= -12/s^5

Answer 12

I think you need to rewrite it first
A(s)=-12*s^-5
then use the exponent rule rule again
so -60*s^-6
Then move it back down
-60/s^6 that what you got?

Answer 13

yeah you are good at this :)

Answer 14

It was actually one of those that brought me to this web site tonight

Answer 15

Are you just working on the exponent rule?

Answer 16

ah ha

Answer 17

yeah there are other one's with radicals

Answer 18

yeah those aren't much fun

Answer 19

yes headache

Answer 20

what is it?

Answer 21

ha its grtting really late over here
S(s)= \[\sqrt{p}- p\]

Answer 22

Oh all mine so far have been in the demonstrator
first get rid of the root it is p^1/2-p

Answer 23

then, get rid of the constant and use the exp rule so
1/2p^-1/2

Answer 24

Sorry it is getting late and figure out that equation thing isn't fast enough lol

Answer 25

yeah the answer was 1/2p-1/2-1 ?

Answer 26

That what the book says?

Answer 27

yeah 1/2 p^-1/2 -1

Answer 28

lol tired, Well good luck with the rest
Night

Answer 29

yeah thank you so much :)

Answer 30
