# Question:Sums of the Vector's Components

## Question:Sums of the Vector's Components

Maple

Hi, I use Maple 13 and have this issue to solve.

In an archive.txt there is the following Vector:

`-1/64*cosdincl^2*cos(2*ele-2*g-2*anom-2*w)+1/16*sinfJ*cosfK*sindincl*cos(2*ele+g-h+om-2*anom-2*w)-1/16*sinfJ*sinfK*cosdincl*cos(2*ele-g-2*h+2*om-2*anom-2*w)+1/16*sinfJ*cosfK*sindincl*cos(2*ele-g-h+om-2*anom-2*w)-1/16*sinfJ*sinfK*cosdincl*cos(2*ele-g+2*h-2*om-2*anom-2*w)+1/16*sinfJ*cosfK*sindincl*cos(2*ele-g+h-om-2*anom-2*w)+1/128*cos(2*ele+2*g-2*h+2*om-2*anom-2*w)`
`(...) etc.`
`What I want to do is:`
`vec:=ImportVector("home/demac/...archive.txt");`
`Then convert this vector in a way I have the sums of the components, like this:`
`expr:=-1/64*cosdincl^2*cos(2*ele-2*g-2*anom-2*w)+1/16*sinfJ*cosfK*sindincl*cos(2*ele+g-h+om-2*anom-2*w)-1/16*sinfJ*sinfK*cosdincl*cos(2*ele-g-2*h+2*om-2*anom-2*w)+1/16*sinfJ*cosfK*sindincl*cos(2*ele-g-h+om-2*anom-2*w)+(...)`
`See that the negaitve components still negative;`
` `
`How can I do that?`
` `
`Thnx for the help.`
