    So can I say ''infinite pieces'' of vertical lines instead of ''almost infinite pieces''?

    to me,,"almost infinite" definitely does not make sense at this stage. 

    but if we  were implying some contexts,for instance, in real analysis (some relevant subtitles would be : lebesgue integral, limits  specifically in this context, lebsgue space,etc.)then I m not sure.

    If ads are enabled, YouTube pays approximately $1 per each 1000 views. So 1 mln views = $1k.

    Professional musicians typically earn money on concerts   and selling CD/MP3.    🚫

    (4000 hours per year, is quite a lot for newbie, it is almost half year of watching by single person, or 4h for each of subscribers)


    concerts seems logical but not so much 🌙, and I do not think that todays musicians are able to ern money via selling cd/mp3 ..I also think that my 7 years old cousin almost will not learn what the cd is. It is odd :) ☢️ :) 

    thanks for the information.

    and are there any statistics taken from youku?

    Also apologies for the slight vagueness, have some linear algebra knowledge however I need to study up on it some more in order to give more concrete terms.


    I think you can find some contexts in Schaum's Outlines / Linear Algebra. (book series)

    if you would like to further improve yourself,then I can recommend Algebra for you under the same source series.

  4. hello,

    I believe I am a good composer and music producer , but unfortunately currently this consists of only a belief. 

    but as you know,all we are trying to implement our plannings and or the things that we imagine.

    Therefore,I am planning to fly to romania. as far as I know ,they are good in popular musics.

    have you any recommendation for me? I shall try to remain open to ideas...

    I think what I am trying to understand is if my interpretation is correct from a beginners perspective. Like if my step my step process is correct vs. if the overall thing is correct. Analogous to trying to initially understand a physics equation intuitively verses begin able to solve it. Thank you both however for the assistance.

    I understand. physics and mathematics are different disciplines. 

    as a matheatician,to me,if you would like to do mathematics ,then you need to concentrate on definitions and theorems.

    I am attempting to understanding implication in mathematical logic.

    I will start off by giving an example of its use and my interpretation of how to correctly under it. That way my process can be critiqued and corrected.


    if "f(a) =f(a')", then " a = a' "


    the given logical statement above is like an "instruction manual" in which if I have f(some a) = f(some b) then it will always result in some a equaling some a'.

    And if I observe a counter example to this then that would mean that the overall example statement is wrong and therefore it is not defined as being that said thing, in this case

    being the definition of a one to one function.

    That being said if I have the function

    f = {(1, a), (2, a), (3, b)} and I do some searching I find that f(1) = f(2). Because of this I can use the above example logical statement.

    if f(1) = f(2), then 1 = 2. However this is not the case and therefore the initial statement is thereby false and thus it is not a one to one function.


    Is this interpretation correct?


    if you meant the derivation function,then your implication is incorrect!

    because  [math] f(2x)=f((x^{2}+c)')  [/math] but   [math] 2x \ne x^{2}+c [/math]

    if you meant whether  1-1 is equivalent of this proposition (given below) ,then yes!

    "f(x)=f(y) --->> x=y"

    but if you are asking whether ,being well defined is equivalent meaning of 1-1 ,then no.

    let see one example given in the figure.

    Yo need another parameter besides C.

    you can use other constants that I did not write. (e.g.: one of other curvature might be written as: x^3 + b ...)

    but this should be written like something this: 

    [math] \frac {x^{2}}{a^{2}}+\frac {y^{2}}{b^{2}}+ \frac {z^{2}}{c^{2}}=1[/math]

    this is elipsoid, but I can't find the correct equation for that curvial object above.


    oh,my hodja from my BSc has replied just now. this thread can be closed ...

    thanks to my lovely hodja.
