Math Is Fun Forum

I have not explained my question properly,

I just want to know what is limit.!
I can`t understnad what is it

and I know I can`t put 0 in that example

But what is the relationship about that and limit?

does the limit mean : x  approaches to a value...
y  approaches to a value ... etc

and ... what is  continuous function.?

sure,

if we want to make straight line by this equation{ y = −2x + 8 }
we just have to choose any value for X then find the value for Y  right?

that is easy, thank you very much for helping me

thank you very much

but I have another question please,

in this picture,

He told me try to make, like :  y = −2x + 8

how to make that in that graph?

does he mean make that equation by play with the graph?
or
in mathematically way like with pen and paper?

Sorry not my focus and my attention to some things ..  I`m Beginner.....

But you will feel tired and stress
I don`t want to take your time learning me,

both of it

I mean : when you see matrices is "mathisfun" and in "wikipedia" which we will perfer ?
Of course the mathisfun
cause it is like a Systematic source and very good at teaching

you mean Massachusetts Institute of Technology,
I will look for it in them site.
I asked somone in the net about studing math, he told me about (Thomas Calculus book)
is it useful book?

but in College of Mathematics
the student study 4 years then 2 then 4 then he will be a Doctor, in the last he will be Scientist in Mathematics!
how would that be, it most a Study plan
I`m study a computer engineering technology and I need math in all of my life but how,

the searching in internet about maths cources is take alot of time!
I've experimented with it
Sometimes up to 4 hours and I wound up not Find Course One !!!!!!!

, I`m loser and in a bad University,

I study matrices from this site "mathsisfun"
and I like that site so much but .. I didn`t found any other Syllabus in it, Like :- (3- Cramer’s rule)....etc

about my University, no they do not teach me anythings I`m from arabian country In Iraq..

Teachers in our university is very bad and do not have the scientific ability to teach students
They're not completing the full articles of our Curriculum,
I'm in deep trouble and I`m trying to help myself,

not just in Mathematics, but in all Threads..
I want to read no just these syllabus .. it is just for specialization, but I want to learn even more..
but I don`t know what books I must read and from where I can begin

and in my city there is no Professionals Computer programmers, and Computer programmers in my college anyone of them didn`t read at least one book about Computers!
