Question

A host of Python questions.

Answer 1

1-In python, how could I code an iterative function upon a number, stopping after x iterations?
2- Is there a way of coding: [if it is before the xth iteration, go back to line a (containing y=f(x)) and make replace x with y]?

Answer 2

Same question, really.

Answer 3

1 there are loops in python too.
2 I am not sure i understand what you are trying to say

Answer 4

Okay, an example: how would you, starting with x_1=2

\[f(x_{n+1})=x_n^2-x_n\]
Do 10 iterations of this function?

Answer 5

Actually, I want\[f(x_{n+1})=x_n-\frac{2x_n^3-9x_n+3}{6x_n^2-9}\]

Answer 6

What is wrong with

i=2
a=0
while a<10:
i = i-(((2*i*i*i)-(9*i*i)+3)/((6*i*i)-9))
a = a + 1
print(i)
