I fully agree with Devy. (tell me if you don't like Devy)-
Every member is important. More members-bigger importance.

If this operation is confusing, you can replace i6t by a function, for example:

Then you should prove that :

which number I can't understand.

Let

If we use the identities:

,
we can have interestiong results:

pp: lots of LaTeX!

The latex goes the page indeed.

something like batch file script?

If q is rational, then q=10 in base q :):)

m may be connected with "multiply" or something
And c is something as constant-it is used very much in calculus it means a free-of-unknowns addend, i think.

What is applescript?

I have a notebook in which the numberof solutions of such equations is given as a recursive formula and generating function.

Good.
