## Thanks good idea, however.....

my problem is thoses students that don't listen to my good ideas. They are working with a non saved document. They have pressed "new document" and then they work, without saving.

And sometimes their MAC (it's always MAC), stoppes, ie. we see that circle going round and round.

## File name...

Is there a list of "no go" characters somewhere?

## I have tried everything of the above...

But nothing so far.

When I use Edit-execute-worksheet - i get "kernel connection lost"

## ?...

Per

## and...

## with the file...

I have tried to make a file and upload it. I hope I succed

## a := [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];b :...

a := [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

b := [300, 170, 90, 55, 35, 20, 12, 5, 2, 1];

db := `~`[`^`](b, 1/2);

db being errors

ErrorPlot(b, yerrors = db)

generates the errorplot.

f(x):=ExponentialFit(a,b,x) generates the function that I want plottet.

## Thanks....

When I get the answer from Support I will write on thes string.

## accuracy...

Well As I see it the problem is, that this solution only works, when you know the result.

What I don't understand is why Maple doesn't get it right.

By using least squares method this will generate 1*x^2 in hand calculation.
