i have 3 equations which contains both numeric and symbols, how can i seprrate these to ?
for example :

> restart:
> eq1:=a[1]^3+a[2]+a[3]^2+50;

> eq2:=a[1]^2+5*a[2]+a[3]+44;

> eq3:=a[1]+a[2]+a[3]^2+74;

i want maple to seprate these three equations in two vectors,first vector including symbols and second one includes numerics , like this :
V1:=<<a[1]^3+a[2]+a[3]^2>,<a[1]^2+5*a[2]+a[3]>,<a[1]+a[2]+a[3]^2>>;

V2:=<<50>,<44>,<74>>;

eq:=<<eq1>,<eq2>,<eq3>>;

so that 

is(V1+V2=eq);

gives me the answer true.
tnx for help.

i do not want maple to round off some terms , for example 1.7777777777 which is rounded off 1.7777777778 . i do not want maple to round off the result,what should i do ?

how can i define an index for a vector?

for example i have

V:=Vector(5)

for i to 20 do
...
V[i]=..

od.

when i write V[i] i want to address it for  "i"'s number from the loop,not element "i" of the Vector. how can i define it ?!
thnx for help 

i have a problem in using command "collect". 

what should i do ? i face this message when i want to solve my equations? can anyone help me ?view the worksheet
