5.13.2 Table of values and graph of a recurrent sequence : tableseq and plotseq
tableseq is a command that should be used inside a spreadsheet
(opened with Alt+t),
it returns a template to fill one column with
u_{0}, u_{n+1}=f(u_{n}) (oneterm recurrence) or
more generally u_{0},...,u_{k}, u_{n+k+1}=f(u_{n},u_{n+1},...,u_{n+k}).
The template fills the column starting from the selected cell, or
starting from 0 if the whole column was selected.
See also plotseq (section 6.13) for a graphic representation
of a oneterm recurrence sequence.
Examples :

display the values of the sequence u_{0}=3.5, u_{n}=sin(u_{n−1})
Select a cell of the spreadsheet (for example B0) and
input in the command line :
tableseq(sin(n),n,3.5)
Output :
a column with sin(n), n, 3.5
and the formula evalf(subst(B$0,B$1,B2))
You get the values of the sequence
u_{0}=3.5, u_{n}=sin(u_{n1}) in the column
B.
 display the values of the Fibonacci sequence
u_{0}=1, u_{1}=1 u_{n+2}=u_{n}+u_{n+1}
Select a cell, say B0, and input in the command line
tableseq(x+y,[x,y],[1,1])
This fills the B column sheet with
row  B 
0  x+y 
1  x 
2  y
