How do I write a recursive golden ratio?
This is my code to compute the golden ratio using recursion written in python but it is not returning me the output that i want. How should i change it?
def recursive_phi(n):
if n<0 or n == 0:
return 0
elif n == 1:
return 1
else:
return recursive_phi(n1) + recursive_phi(n2)
return recursive_phi(n)/recursive_phi(n1)
recursive_fib(10)

It looks like you're trying to use the fact that you get the golden ratio if you divide two consecutive numbers in the Fibonacci sequence?
Since I don't know any Python I have to cheat and search internet,
https://www.programiz.com/pythonpro...accirecursion
Code:
def recur_fibo(n):
if n <= 1:
return n
else:
return(recur_fibo(n1) + recur_fibo(n2))
This then will produce the golden ratio,
Code:
def recursive_phi(n):
return(recur_fibo(n) / recur_fibo(n1))
If it works it proves Python is so easy you don't need any Python knowledge at all to use it.

Re: How do I write a recursive golden ratio?
If you just need the golden ratio then it can be calculated easily as
(1 + sqrt(5)) / 2
See https://www.mathsisfun.com/numbers/goldenratio.html

Re: How do I write a recursive golden ratio?
Exploring the elegance of recursive algorithms, crafting a recursive golden ratio is a mesmerizing journey into the harmonious world of mathematics. It's akin to composing a symphony of numbers, each iteration revealing a deeper layer of beauty. Embracing the Fibonacci sequence and the divine proportion, the recursive golden ratio becomes a poetic dance of numbers converging towards perfection. The recursive approach adds a layer of complexity, elevating the challenge and the joy of unraveling its mysteries. As you embark on this intellectual adventure, remember that every line of code is a stroke on the canvas of your creativity.

Re: How do I write a recursive golden ratio?
I think it will look like:
def recursive_phi(n):
if n < 0:
return 0
elif n == 0:
return 0
elif n == 1:
return 1
else:
return recursive_phi(n1) + recursive_phi(n2)
def golden_ratio(n):
return recursive_phi(n) / recursive_phi(n1)
print(golden_ratio(10)) the decision did not come to me immediately, it did not come immediately. It came after my studies personal statement residency writing service It was very appropriate, because it was a kind of help for me ..
