It works now.

In trying to access the contact form your refer to, I receive an access denied message saying:

Happy to hear that it made a difference to you.

Thanks for that significant improvement.

I think I now understand the true intent of the exercise: Replace the codes in my former post by

Fouriercoeff := proc(f)
	1/Pi*int(f,x=-Pi..Pi),
	seq(1/Pi*int(f*F(n*x),x=-Pi..Pi),F in [cos,sin])
end proc:

and

a0,an,bn := Fouriercoeff(x^2);

and

N := 10:
expr := a0/2
	+ add(eval(an,n=i)*cos(i*x),i=1..N)
	+ add(eval(bn,n=i)*sin(i*x),i=1..N);

I agree with you concerning the pre-tag.

Actually, having this made available as a button in the new editor would be an improvement over the old one, where it was not so even though the pre-tag was/is very much used.

That was exactly what I meant: not to have to assort to manual insertion of code-tags in source-view.

To be able to change the font is nice because it makes this (mathematical) x stand out against this (non-mathematical) x.

Maybe my Maple to LaTeX converter which cleanly converts various expressions to LaTeX could have your interest.

Previous to my original posting, I actually did think about apply and unapply, but I didn't manage to make it work. Thanks for showing me how to.
