Question

Sigh no questions today? Anyone want to help with calc : D

Answer 1

give me a question and lets c if the random stuff i learned over the years helped

Answer 2

lol
find the derivative of
y= (2x-7)^3

Answer 3

no idea so what does derivative mean XD

Answer 4

lol when no one can answer it so i answer it myself

Answer 5

XD

Answer 6

wish i could give myself a medal

Answer 7

You are required to use the chain rule, of function of a function rule here.
Remember the power rule is
\[y = x^n \rightarrow \frac{ dy }{ dx } = nx^{n-1}\]
Similarly if instead of x, you have f(x) raised to a power:
\[y = [f(x)]^n \rightarrow \frac{ dy }{ dx } = n [f(x)]^{n-1} \times f'(x)\]

So treat like your normal power rule but make sure you multiply the result by the derivative of the base i.e. (2x-7)
This extra multiplication step by f'(x) is part of the chain rule/FOF rule

Answer 8

aint that complicated mww thanks for helpin though haha

Answer 9

i guess im just bored, posting questions then answering it myself

Answer 10

ikr now I'm scared of passing i don't want to do calculus maybe i should just fail XD

Answer 11

calculus is not too tricky (at least elementary calculus covered in Calc I and II) if you get the principles and the rules (and they are a finite bunch)

Answer 12

nah @OtherWorldly aint hard

Answer 13

all it is...a lot of formulas thats it

Answer 14

Wow that makes me feel SO MUCH BETTER

Answer 15

lol

Answer 16

the formulas are actually shortcuts to more rigorous first principles so in a way we have it easy.

Answer 17

Idk why but even if u guys say its easy I'm always going to think its hard NO MATTER WHAT calculus is a mind killer to me

Answer 18

well if you wanna catch up to me... take calc next year :D :D :D

Answer 19

i took trig honors freshman year

Answer 20

no way XD dude ur too smart

Answer 21

thanks, wow theres a lot of bored people

Answer 22

lol yup

Answer 23

when openstudy turns to a chat room

Answer 24

barely anyone is on on weekends

Answer 25

hey yall in the audience, anyone want to try a calc problem? ill post one up if anyones bored

Answer 26

i can try teaching people calc :D

Answer 27

yeah for a price XD

Answer 28

ok here goes
g(x) = 3 (4-x)^4

Answer 29

find the derivative using the chain rule

Answer 30

yeah about that i don't really understand the chain rule sooooooo

Answer 31

@OtherWorldly see a pattern with the exponents?

Answer 32

maybe..........yeah ok i don't

Answer 33

when you derive, you subtract one from the exponent

Answer 34

the ' means "prime", which is the first derivative

Answer 35

yeah i can't do this i can't get it if i don't understand the rule I'm just gonna stick with Algebra

Answer 36

haha

Answer 37

pretty sure u tried ur best teaching me GOOD JOB TEACH sorry i don't got money on me can't pay the price of u tutoring me XD freebie?

Answer 38

haha sure, ill charge you 500 medals though

Answer 39

XD i got all my life to pay u back but can i make installments XD

Answer 40

haha

Answer 41
