You may use integration by parts but for
q := Int(1/ln(t), t = exp(1) ..  x);

and then get rid of the constant (which does not matter).

@rlopez 

The problem with this approach is that all the integrals (except q itself) are divergent (even as Cauchy Principal Value) for x>1.

@Kitonum 

No, it is in the source code of GAMMA.

@Kitonum 

This is by design because GAMMA increases very fast.
If you really want such huge numbers then set (not recommended):

`GAMMA/magic`:=100,100,infinity,50;

and use s(100);

@J F Ogilvie 

For many users the xxx__yyy typesetting convention seems to be just enough. I don't see any reason to sacrifice the table functionality for the sake of typesetting. And even without xxx__yyy: why should it be so difficult to use names with more than one letter; must they be exactly the same as in a published article? This is anyway impossible because in many cases in articles the symbols are context-sensitive.

@tomleslie 

But

simplify(subs(z = -z, sin(z)));  # ==>  - sin(z)

(automatic simplification)

It is only (4.)  which intrigues me because simplify usually distributes over operands.

map(simplify, (sqrt(1-I)*sqrt(1+I)-sqrt(2))*(t+1));  # ==> 0

Nice remark. An even shorter procedure is

MaxL:= (a,b,c,r)-> sqrt(a^2+b^2+c^2)-2*r*sqrt((a^2+b^2+c^2)/min(a,b,c)^2-1);

What about 34234-2*17117 ?

BTW, F(a) = Kitonium's f(a),  but you think f is better.

@Kitonum 

This one is simpler and works for symbolic entries too:

F := a -> piecewise(is(a,odd),{(-a+1)/2,(-a-1)/2},{-round(a/2)});

Do you use a random generator for functions of two variables?

@Jjjones98 

Then write S(n) as

Sum((1/k^0.1)*(sin(1/k)-1/k), k=1..n) +  Sum(1/k^(11/10), k=1..n);

The fist sum has a rapid convergence; for the second one use:

asympt(Sum(1/k^(11/10), k=1..n),n);
 

@Kitonum 

Actually the symbolic solution is probably useless (being too long) even without parametric and allsolutions.

Apollonius (of Perga) lived more than five centuries before Pappus.

Do you think that Maplesoft should invest a so much effort for typesetting?
Typesetting is a nice feature but I think that an excessive fine-tuning is too expensive.
I'd prefer these efforts be directed towards maths.
And anyway, Maple is not going to compete with LaTeX.
By the way, wouldn't it be more natural a LaTeX convention in the case of atomic variables?
It is not comfortable to use names like  `#msub(mi("x"),mn("1"))`  (in 1D notation)
(of course a macro() can be used here but even so...).
