Same thing with Mathematica 10.2 under OS X 10.10.5.

comment What kind of creature is h[c] for definition h[c_][x_] := (* function of x and c *)
If one is going to regard h as a parameterized function, i.e., a family of functions, then one might as well use a subscript definition: Subscript[h, c_][x_] := (x + c/x)/2, so that StandardForm notation such as $h_2$ resembles a traditional mathematical notation for one of a family of functions.

comment What kind of creature is h[c] for definition h[c_][x_] := (* function of x and c *)
@Jens: Yes, I definitely like calling h a "parameterized function", with the 2 in h[2] a value of the parameter. I'm beginning to sense that it makes little sense to ask what h[2] is other than to say it's a function and look at h[2][x] or h[2][1], etc. -- no more sense than to ask what, say, Sin "is".

comment What kind of creature is h[c] for definition h[c_][x_] := (* function of x and c *)
I think a good way to rephrase my technical question is to ask: "How would you explain to a Mathematica beginner what the object h[2] is?"

comment What kind of creature is h[c] for definition h[c_][x_] := (* function of x and c *)
@Jens: the "closely related" post you cite tells me something I already know, namely, that SubValues[h] gives what I expect. But it still doesn't say anything about what h[2] is.

comment What kind of creature is h[c] for definition h[c_][x_] := (* function of x and c *)
@ciao: Yes, I know what I get for h[2][y] or h[2][x], etc. But how can one characterize h[2] itself? That was my question.

Actually, the method is widely cited as "Hero's Method", e.g. in en.wikipedia.org/wiki/Methods_of_computing_square_roots. And it's also knows as the" Babylonian method". But yes, the English transliteration of the Greek name Ἥρων" is "Heron".

comment How to determine if a function is continuous?
Can you give a specific example of defining in Mathematica the sort of function $g$ you want to test?

comment Define function of two variable like a vector
Once you have the function phi defined, as @belisarius indicates, you may take its partials like this: D[phi[u, v], u] and D[phi[u, v], v].

You don't have functions a[t], b[t] produced by your code, just two individual numbers, a and b with values 2.45035 and 0.0609429, respectively.

comment Put webMathematica folder outside Tomcat webapps folder?
Alas, I don't comprehend how to put the "this" and "no. 4 in this" together for the situation I describe. Don't I need, also to add an entry such as 127.0.0.1 webmathematica.local to /etc/hosts and a corresponding VirtualHost entry to apache2/conf/extra/httpd-vhosts.conf?`

comment Put webMathematica folder outside Tomcat webapps folder?
No, that's not working (OS X 10.10.4) even if I keep the webmathematica folder in its default position /usr/local/apache-tomcat-7.0.37/webapps and use that location in the docBase value in the file ` /usr/local/apache-tomcat-7.0.37/conf/Catalina/localhost/ROOT.xml` that you describe. After restarting Tomcat (and apache), browsing to localhost:8080 still brings up the default Tomcat page, not the webMathematica page.

Will you be happy with an inverse function involving ArcTan? If so, try InverseFunction.

comment find the inverse of a hyperbolic function
Please post with actual and correct Mathematica code, e.g., use Tanh[d (x - g)] rather than $tanh(d(x - g))$. Also, what are your $d$, $m$, and $g$ — particular constants or arbitrary constants (perhaps with some conditions placed upon them)?
