## A question about obtaining result in int...

Maple 18

Excuse me,

I have the following input

***

fff:=x1^k;
int(fff,x1=0..x2);

***

I would like to obtain

1/(k+1)* (x2^(k+1)), k<>-1

but maple gives me just the same integral. Is there any way to get the expression?

Thank you!

## Readdata with something like 10^-6...

Hi,

I would like to readdata from a file

-6
2 0.38 10 + 0. I

I use

for i from 1 to 20 do
print(i,f[i]);
end do:

The problem is, seems maple get -6, instead of 10^-6, since the .txt file puts -6 in a row.

My question is, how to get the right data 0.38*10^-6 correctly?

P.S. I used cmaple  inputfile >  outputfile.txt to get the .txt file. Should I use writedata?

## How to skip comma in readdata...

Maple

Hi,

I have a file "d:\\test.txt", the content is

1, 2.0000 + 0. I

then I use

for i from 1 to 1 do
print(i,f[i]);
end do:

it gives me

***

[[1.]]
1, [1.]

***

If I remove the comma in the file, I could obtain 2. I do not want to do it manually that remove all commas by hand. Is there any way to skip the commas in readdata?
