Hi, how to find the root of the following function by fixed point iteration method ?

-exp(1/(3*exp(t)))/(3*exp(t))

hi Hannibal lecter

I'm having trouble sorting out all those brackets and powers. Is this your function?

That function doesn't have any roots, so any such iteration will simply diverge. Did you write the function correctly?

it's the original function : ?−? = 3ln(?)

and that's is the function in another form :

(exp(exp(-t)/3))
