So the number 1 means that the sequence 010 appeared in pi?
In the first 10000 digits, you expect this about 100 times. The same for 2 through 9. In fact, then, 1 through 9 are in the upper left (log 9 = 2.2), each with about 100 hits. Next, 11 through 99 (log 99 = 5.6), each with bout 10 hits. Then we expect 111 through 999, each with about 1 hit (log 999 = 6.9) and above that only every tenth number up to 9999 gets a hit.

Don't these two contradict each other?
*u3d became a popular format*
and
*only CAD and Framemaker seem to have u3d export*

This should already work in Maple on Mac. In all mac applications, when you "print",
you get the option of printing to a PDF file instead of paper.

Maple may say that 0^0 is 1, but it doesn't say that for 0.0^0.0;
The definition for a^b where the exponent b is complex is
a^b = exp(b*log(a)), so it should be undefined for a=0.
> 0^0;
1
> 0.0^0.0;
Float(undefined)
> subs(x=0,sum(x^k,k=0..4)) = sum(subs(x=0,x^k),k=0..4);
1 = 0
> 0^(1+I);
0
> 0^I;
Error, numeric exception: division by zero
> 0^(-1+I);

I think he wants to input an equation like
eq1 := A*B = C;
or maybe . or &* or some other symbol for the multiply.
Here A, B, C are just letters. We know they are matrices, but
Maple has not been told a size or anything like that.
Then he wants to enter
solve(eq1,B);
and get the result
inverse(A)*C
or maybe something other than "inverse"
We want to "solve" for a non-commutative multiplication.
There is a way to define your own operations, and give them properties.
But can you give them an "inverse" and then solve as above?

** so ... I I would have < a > defined and also defined .. and if the value of t would change I would be able to find the answers ... what happens if In my equation I have a polynomial ..... of I juste have the A pressent**
I am sorry. i do not understand your English.

For Maple, write it with ( ) rather than _ , though.
> `rsolve({y(t)-a*y(t-1)=A*p^t,y(0)=y0},y(t));`

y0*a^t+A/(-p+a)*p*a^t-A/(-p+a)*p*p^t

**
f=1000*x+7500*y
under constraint:
g=10000000-(20000*x^0.8)*y^1.2
**
I guess your problem is trying to find a nonexistent solution.
As x -> 0, y -> infinity and f -> infinity. There is no maximum.
There is a minimum value of 1.46*10^5 at around x=58,y=12.
Is that what you wanted to find?

[[being of an engineering background, most of your list do not resonate with me ]]
I remember once talking with an astronomer, who was surprised to find that I considered Gauss to be a mathematician rather than an astronomer.
