Question

okay who can help me?

Answer 1

Me but it depends with what

Answer 2

f(x) = cos x − sin x, [0, 2π]
use MVT to find a point that satisfies c.

Answer 3

\[\frac{f(b)-f(a)}{b-a}=f \prime (c)\]
do f(b) and f(a) first a=0 b=2pi

Answer 4

@dleather25 waiting for you response

Answer 5

yes! they do

Answer 6

no I believe I asked you to calculate f(b) and f(a)

Answer 7

ok well I tried to help you..... good luck

Answer 8

2pi -0 - 0 - 2pi/ 2pi - 0

Answer 9

do them separate please
what is f(b) equal to?
what is f(a) equal to?

Answer 10

f(b) = cos x i guess and sinx = f(a)/

Answer 11

f(b)=f(2pi)
f(a)=f(0)

Answer 12

okay, so now the derivative of sinx - cos x = something..

Answer 13

no you still did not tell me what they are equal to?
state each one please

Answer 14

sin 2pi = .109

Answer 15

cos 2pi = .99399

Answer 16

cos (0) = 1

Answer 17

sin 0 = 0

Answer 18

1- .109 = .891

Answer 19

.891/2pi

Answer 20

is that good?

Answer 21

no do you not know the exact values of sin(0), cos(0), sin(2pi), cos(2pi)?
I hope you are not taking the AP exam for calculus

Answer 23

??? What? Do you know the answer, I've been in a library for 3 and a half hours doing my calculus homework, and have no clue how to do this problem, f(b) - f(a) / b-a = f ' (c)

Answer 24

f(b)=f(2pi)=cosp(2pi)-sin(2pi)=?
f(a)=f(0)=cos(0)-sin(0)=?

Answer 25

yes, I know a bit about MVT

Answer 26

.88455

Answer 27

You still need to answer the above part so we can move on.
no, go to the website I posted and look up these exact values?
AP calculus will not accept that, neither will any college professor

Answer 28

ok cos 2pi = .9939931166 and sin 2pi = .1094426069 so .9939931166-.1094426069 = .8845505097 / cos(0) aka (1)

Answer 29

did you go to the website? There are no decimals - those values are approximations
we want exact solutions, did your precal teacher not show you how to derive those values using the unit circle????

Answer 30

no? just use decimals? what does it matter..

Answer 31

it matters !!! please go to the website and look at those values.

Answer 32

ok and sin 0 = 0 and cos 0 = 1...

Answer 33

now calculate f(b)
and f(a)

Answer 34

ok good bye!!!

Answer 35

what are you talking about i did!!!!!

Answer 36

why dont you calculate it? obviously i dont know what the heck you're talking about so you do it and tell me how you did it/

Answer 37

no f(b) = look above when I stated it and had a ?
no f(a)= same comment

Answer 38

so sin 2pi = ???

Answer 39

go back to that website

Answer 40

sin 2 pi = 0

Answer 41

f(b)=f(2pi)=cosp(2pi)-sin(2pi)=?
f(a)=f(0)=cos(0)-sin(0)=?

Answer 42

waiting .............
f(b)=f(2pi)=cosp(2pi)-sin(2pi)=?
f(a)=f(0)=cos(0)-sin(0)=?

Answer 43

.99 - 0 = .9939 blahhh...

Answer 44

did we go back to decimal?
decimals are bad, begone decimals.

Answer 45

cos 2pi = 2pi??

Answer 46

really???? Maybe you should attend tutoring with your teacher or ask one of your friends. I really must go........ :(

Answer 47

what is the answer

Answer 48

sorry, I am not interested in giving the solution. I am only interested in the process and helping you learn. Last post, I will not respond anymore

Answer 49

Read the rules of behavior...... I have reported you for abuse

Answer 50

I dont even care man, how you gonna just leave like that, i dont come here just to waste my time
