Question

derivative of 5/(2x-3)^4

Answer 1

since it's in a fraction form you can take the following:

u = 5
u' = 0
v = (2x-3)^4
v' = (4)(2)(2x-3)^3

now substitute all of them in the general formula of the derivative which is :
\[= (u'v - uv')/v^2\]

give it a try ^_^

Answer 2

can you believe it? I knew how to do this 4 days ago but now I forgot the rules!!! Something is wrong with my mind, I think I am learning too many things at the same time

Answer 3

that's why I told you to take it easy. Take a break now andy, so that your brain rests. ^_^ and after that, you can revise the formulas and questions to refresh your information :)

Answer 4

ok buddy, I will do that now (btw, for the past week I only slept afew hours a day and never went to sleep before midnight)

Answer 5

....seriously, If I were there right now, I'm sorry but I would've slapped you

Answer 6

Don't worry about time! Consider time as your friend, organize yourself and sleep atleast 7 hours.

Answer 7

many ppl have tried to slap me, but unfortunatelly all of their efforts were stopped before they even knew it =D LOL

I know about time, but life is so short and there are so many things to learn and do :)

Answer 8

life is too short, so value the moments and time you spend in it!

Oh believe me, I'll try every way to get you down.

Answer 9

:O You will try every way to GET ME DOWN? =D
*wondering*

Answer 10

oh you have no idea. Yes I can be nice, sweet and gentle, but when I HAVE to, I get quite the opposite.

Answer 11

only when I really have to.

Answer 12

I will tell you one of the martial secrets:
-Calm and focused mind is stronger than a warriors sword

Answer 13

okay so so far I have (0(2x-3)^4)-(5)(4)(2)(2x-3)^3, do I multiply the (5)(4)(2) by the (2x-3)^3?

Answer 14

sorry jfive for interupting

Answer 15

yeah yeah , but I just kick when I have to.

Answer 16

wait lol, didn't calculate it yet

Answer 17

so, you would like, just come at me and kick me? just like that?
=D

Answer 18

I only kick when the situation get's really delicate, if you know what I mean. Since the every man's weakness is known, but when it comes to the other normal things, like exhausting yourself and blah blah blah. I talk, again and again till you listen, if not, then I get so serious.

Answer 19

sicne every*

Answer 20

if my slap is stopped, I tackle, if my tackle is stopped, I just jump on you lol

Answer 21

why don't you guys just pick up the phone or maybe hit up yahoo messenger? I was sort of asking for help

Answer 22

sorry! , did you substitute the given in the equation? if you did, then don't need to simplify, keep it as it is :)

Answer 23

What do you mean by the given?

Answer 24

what I wrote in the top :)

Answer 25

you know , u u' v and v'

Answer 26

^_^

Answer 27

:) nice.
but if I were you, I would never use kicks UNLESS the opponent is compleately dull and slow, or is really really week, OR you are really good at them.
Because the opponent can catch you leg, and then put you down, so kicking is not really effective unless you are really fast. Better use punches to the head or neck, and only use very low kicks to the knees (because once you mess up someones knee, he will go down instantly).

Answer 28

yep I substituted all that in, I'm just having trouble with the simplifying

Answer 29

oh don't worry, I'm a pro at kicking.

Answer 30

lol no need to simplify, you can keep it as it is

Answer 31

Oh, ok then.

Answer 32

that's what my teachers used to say ^_^

Answer 33

been kicking all my life

Answer 34

well , almost

Answer 35

i'm getting -40(2x-3)^3/2x-3 to the whatever

Answer 36

lol, to the 2, but what happened to the other part in the top? u'v?

Answer 37

there is a difference between kicking, and kicking correctly

Answer 38

oh I don't care, as long as I get out of the hideous situation. If my kick fails, I can think of something else .

Answer 39

the derivative of u is zero so wouldn't that just equal zero when multiplied

Answer 40

lol, right forgot ^^" so your answer is correct ^_^

Answer 41

alright now, the denominator squared, my algebra-fu is weak, would that be (2x-3)^8?

Answer 42

yep :)

Answer 43

it's alright, practice makes perfect. Just practice and you'll get alot better ^_^

Answer 44

in real life situation, I would recoment groin kicks (if you are far enough) or groin knee kicks (if you are close). Also biting, screaming loud (affects the opponent psychologicaly) and eye gouging can be lifesavers too. Once the oponent is full of pain, you can finish the deal with a double spining hook kick.

Answer 45

yeah the end of the semester is upon me so not much time to practice

Answer 46

practice DOES NOT make perfect,
PERFECT practice makes PERFECT

Answer 47

I don't scream, but i do bite if the kick doesn't work.

Answer 48

=D ancient knowledge of martial artists

Answer 49

practice makes perfect because the more you practice the more you are getting closer to perfection andy

Answer 50

nope, and I can prove my point

Answer 51

all ears

Answer 52

lol, wait I got wat you mean

Answer 53

but same thing, arg>_< LOL!

Answer 54

lets say a teenager wants to become a basketball star, then he is training every day, for 5 hours a day, and putting ALL his efforts into it. However, he does not have anyone to teach him the right throwing technique and strategies. The longer he trains the more his nervous and actuation systems get used to the teqniques he uses (even though they are not right or effective) and he also creates his own strategies for playing. He never trains with a full team as he does not have enough friends who would train with him. His team-skills are very low. After he finishes high school, do you think his efforts and hard work and LOTS of practice will give him perfect basketball skills? do you think he will be able to play in a team as well as the other student who used PERFECT practice with an experienced trainer? this is why I say that practice is not enough, we need to practice proparly in the perfect way in order to develop a perfect skill.

Answer 55

I think you get my idea. This is just one scenario out of billions, or should I say infinity..

Answer 56

yes I do :)

Answer 57

wow, you are typing alot =D

Answer 58

I am? ._.

Answer 59

oh nvm ^_^" got what you mean now, nothing else to say lol
