The complex recurrent sequence

Parent Previous Next

This is a sequence defined through a formula type of u(n+1) = f[u(n)] where f refers to a complex function already defined.

Such a sequence u is created via icon .


A dialog box pops up.


You are asked for :


The indexes of the sequence start to zero.


When a sequence named u has been created, you can refer to term of index n of the sequence in a calculus as u(n). This term will exist only if n is in the range from 0 to N - 1, where N is the number of terms of the sequence (assuming the term exist).
