#2 Re: Help Me ! » what is the maximum expected slope for a function? » 2017-11-19 09:24:52

can you calculate it to me in details please,,

is it = 1? my textbook say , it's 1

is that right?

please calculate it to me so I'll be able to solve other questions and examples .

hi, how to find maximum slope for a function like " f(x) = x - cos(x) "

can you help me with that please??

#5 Re: Help Me ! » what is Brute-force search in numerical analysis, » 2017-11-08 10:15:13

is all functions easy to solve like that one? or there is a difficulties with other types ,
please give me a textbook to read it
I search a lot I didn't find ,

#6 Re: Help Me ! » what is Brute-force search in numerical analysis, » 2017-11-07 09:07:28

can you give me a simple question equation with it's answer, maybe I will understand ..
because I read a lot about it but all what I read is different from this

for example f(x) = cos(x)-x
how to apply brute-search for this equation?

#7 Re: Help Me ! » what is Brute-force search in numerical analysis, » 2017-10-29 23:19:52

I can't understand this,
can you please give me a textbook to read or a website ..

Hi, I'm in a hurry,
how to find order of an recurrence relation
for example :
an= an-1 + an^2-2
there order of this function is "2"

how is that be?
and what is the meaning of order

Hi, is the a difference between Linear Recurrence Equation and Linear equations???

or they are the same..?

and what is the Linear Recurrence Equation ?

and the important thing I need to know about is : How do we know if it is Linear Recurrence Equation or non-linear?

#14 Re: Help Me ! » HI please solve this absolute value equation with interval notation .. » 2017-02-02 10:48:26

I wrote it in the exam {k = -4}, {k = 1} like you did, and my teacher did,
but I copy it wrong here for you believe me! ....
these number not important,

the important is... the first step cause he want the first step to be right...

so, 

and not the lim L.H.S = lim R.H.S ( like I said)

so the teacher is right in the first step right?

sad

he don't want the  final answer.. he want the first step, he is make excuses to give me 0 ....
so now I can't say   

???

#15 Re: Help Me ! » HI please solve this absolute value equation with interval notation .. » 2017-02-02 08:05:38

so, what is your explanation for this now please?
tell me please everything in one post. I have to finish what began.

I need scientific reasons to proof my solution that is right and not wrong,

because the the Associate Dean for Academic Affairs((he is an professor in mathematics)) and the Dean of the university
say to me that your answer was wrong????????????

please help me they all against me, they say the end of the result is right but when I said ( Limit R.H.S = limit L.H.S) that wrong and you must write it (LIMIT L.H.S = f(0) )  .

please Help me!  Put yourself in my place, what would you do with them?

please ! I'm weak and they are Dr and  Professor and lecturer all against me or against one that maybe wrote a simple mistake

#19 Re: Help Me ! » HI please solve this absolute value equation with interval notation .. » 2017-01-31 10:16:19

I don't have any Idea please help me the course will end in the end of the week so I will not be able to change my marks......

please!!!

#21 Re: Help Me ! » HI please solve this absolute value equation with interval notation .. » 2017-01-30 12:01:21

but I saw a lot of textbook that,  they toke the Limit or the R.H.S cause x ≠0 she these example please :

http://archives.math.utk.edu/visual.calculus/1/continuous.5/

https://www.math.ucdavis.edu/~kouba/CalcOneDIRECTORY/continuitydirectory/Continuity.html

#22 Re: Help Me ! » HI please solve this absolute value equation with interval notation .. » 2017-01-30 09:53:36

if the Limit does not exist can we say just k^2+3k-3 = 0  (just make it equal to zero then find the solution it if can be)

or we can't?...................(1)

so now I understand.... the limit does not exist because x approaches to 0

.I'm afraid maybe he will change his answer again and tell me like what did you told me and he will say you must write in your paper (there is no way to find k ...............(2)  ) sad(

thank you very much

do you mean when I have x in the second H.S I can't tell (limit L.H.S = limit R.H.S)

I did not say that. There are so many things wrong with his question it is difficult to explain away each one.

First, let me say in light of what I was told, my answer, your answer and his answer are all incorrect.


no no sorry I didn't mean by that.. I just asked a question ( do you mean ...)

sorry it is my bad language and I didn't understand you so well because my bad translation sorry again...
it was just a question,...

so what is the correct answer..
and what is the wrong in his question

if the question was wrong how do I'll get the 10 marks hehe!!
what to do please help me in everything you can
and what is the k value???

In this position, do I have to take the limit R.H.S or the f(0)?

As I understand them those two things are not interchangeable.


do you mean when I have x in the second H.S I can't tell (limit L.H.S = limit R.H.S)
I have to say ( f(0) = R.H.S)

cause when we will have x inside this so : (xk^2+k-3)

and when we will take the limit L.H.S = Limit R.HS s0 ..
limit x+1 = limit xk^2+k-3       ((x apro to 0)
1= 0 + k- 3
k=1+3 = 4

is that right? or it will be wrong...

just tell me this please..

#25 Re: Help Me ! » HI please solve this absolute value equation with interval notation .. » 2017-01-29 20:36:29

I told him it is the same, He told you did a crime in mathematics science when you wrote it like that!!!
He want excuses just that..
anyway lets close this section I'll will deal with that problem and I will refer my rights in my way
_____________

I have another question please ...
lets suppose there is x in the question (xk^2+3k-3)
In this position, do I have to take the limit R.H.S or the f(0)?
