In this assignment I have completed all the problems except this one. I have to create a python script to solve an equation (screenshot).
Unfortunately, in my research all over the internet I cannot figure out how in the world to either convert ln to log or anything usable, or anything. The code I have written so far is below. I will also post the answer that our teacher says we should get.
import math p = 100 r = 0.06 / 12 FV = 4000 n = str(ln * ((1 + (FV * r) / p) / (ln * (1 + r)))) print ("Number of periods = " + str(n))
The answer I should get is 36.55539635919235
Any advice or help you have would be greatly appreciated!
Also, we are not using numpy. I already attempted that one.
math.log is the natural logarithm:
math.log(x[, base]) With one argument, return the natural logarithm of
x (to base e).
Your equation is therefore:
n = math.log((1 + (FV * r) / p) / math.log(1 + r)))
Note that in your code you convert n to a
str twice which is unnecessary
Here is the correct implementation using numpy (
np.log() is the natural logarithm)
import numpy as np p = 100 r = 0.06 / 12 FV = 4000 n = np.log(1 + FV * r/ p) / np.log(1 + r) print ("Number of periods = " + str(n))
Number of periods = 36.55539635919235
