    Definition in maths

    Hello,


    I have a very general dude. Is a definition something that we put because is advisable and it can't be deduced?


    Thanks for answering.

    Define (verb), Definite (adjective), Definition (noun):
    from Latin de (q.v.), a preposition with many mean-
    ings, both physical and abstract, and finis "end,
    boundary, border," of unknown prior origin. When
    you define something you "put boundaries around"
    what it can mean. A good definition puts an end
    to confusion about what a tenn means. In calculus,
    a definite integral has numerical limits or "bound-
    aries" on it, as opposed to an indefinite integral.

    My knowledge of maths is very superficial. I am just a beginner in maths. That was the best explanation I could produce with my mediocre knowledge.

    Re: Definition in maths

    In mathematics to "define" something is to explain what that something is in such a way that it can't be interpreted as something else.

    For example, we define a unit circle to be "the locus of all points that are exactly one unit away from a single point".

    Do you have any confusion about what a unit circle is? No, because we have explained what it is in such a way that nothing else could possibly be a unit circle.
