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.

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).

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

You can just use the word argument, then.

You're welcome.

Hi;

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