hi friends

i have a problem in maple with an error

Read'dsnumsort.map';

dsnumsort(Ns(0),[x,y,z]);

for i from 0 to 1000 do;

T:=i/25;

NsT:=Ns(T):

X[i]:=rhs(NsT[C1]); Vx[i]:=rhs(NsT[V1]);

Y[i]:=rhs(NsT[C2]); Vy[i]:=rhs(NsT[V2]);

Z[i]:=rhs(NsT[C3]); Vz[i]:=rhs(NsT[V3]);

KepVec[i]:=convert(crossprod([X[i],Y[i], Z[i]],[Vx[i],Vy[i], Vz[i]]),list);

KepAbs[i]:=norm(KepVec[i],2);

od:

pacecurve({[seq(X[i],Y[i],Z[i],i=0..1000)],[[-1/(2),0,0],[1/(2),0,0]]},labels=['x','y','z']);

but i see:

Error, invalid input: seq expects 2 arguments, but received 4

can you helpe me?

Thanks
