I would like to iterate a function:
def f(x):
return( (1/5)*(x**3+x**2-3) )
f(0)
Running evaluate on the above yields the quantity -3/5. Rather than
evaluating f(-3/5), is there a way to reference the previous output
from evaluate, i.e. to evaluate f(previous) or some similar syntax?
Similarly, is there a way to use the syntax "for i in range()" to
define the next i as f(i)? I know that "for i in range(-2,2,i=f(i))"
does not work. I've briefly searched the tutorial, this Google group,
and Google generally without finding solutions. However, today is my
first day using Sage.
I'm running Sage 4.1.2 pre-compiled 32 bit binary for Debian Lenny.
Thanks.
