Terminology

Hi there. I haven't been here in a while.

Is there a proper name for the interior part of a trigonometric function or is it simply called the inner function, or something to that effect? I have looked around online for an answer but I can't seem to find anything.

For example, the function



does g(x) have a proper term or name? Or is it just "the inner function"?


Thank you very much.

Re: Terminology

You could say g(x) is the argument of the tangent function, but I don't think there is a proper name for such a function g(x).


The limit operator is just an excuse for doing something you know you can't.

Re: Terminology

Thank you, anonimnystefy. I am writing a paper and just wanted to use the correct word, if one existed.

Re: Terminology

You can just use the word argument, then.

You're welcome. smile

Re: Terminology

Hi;

Since this can be thought of as function composition you will sometimes see it called the inside function or first function.


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
