[solved] – Question 99660
Hi, I had a homework to do which I don’t quiet understand. It’s this
Write a function approx_ln(x,n) that approximates the logarithm by n steps
of the above algorithm
with these information
It is based of computing the arithmetic and geometric mean of two values ai, gi
For a given value x > 0, initialize a_0 =(1+x)/2 , g_0 =√x,
• Iterate a_(i+1) =(a_i+g_i)2 and g_(i+1) =√ai+1gi
• Consider ( x−1)/a_i as an approximation to ln(x).
and after trying a lot I came up with this
def arithmetic_geometric_mean(a, g):
while True:
a= (a+g)/2
g=sqrt(a*g)
yield a, g
tol= 1e-5
def approx_ln(x, maxit=500):
a_0= (1+x)/2
g_0=sqrt(x)
for a,b in islice(arithmetic_geometric_mean(a_0, g_0), maxit):
if abs(a-b)<tol:
return (x-1)/a
which works but the question asks for different values of n and idk what to do

Describe the difference between a chained conditional and a nested conditional. Give your own example of each.
Deeply nested conditionals can become difficult to read. Describe a strategy for avoiding nested conditionals. Give your own example of a nested conditional that can be modified to become a single conditional, and show the equivalent single conditional.

1. Copy the countdown function from Section 5.8 of your textbook.
def countdown(n):
if n <= 0:
print(‘Blastoff!’)
else:
print(n)
countdown(n-1)
Write a new recursive function countup that expects a negative argument and counts “up” from that number. Output from running the function should look something like this:
>>> countup(-3)
-3
-2
-1
Blastoff!
Write a Python program that gets a number using keyboard input. (Remember to use input for Python 3 but raw_input for Python 2.)
If the number is positive, the program should call countdown. If the number is negative, the program should call countup. Choose for yourself which function to call for input of zero.
Provide the following.
- The code of your program.
- Output for the following input: a positive number, a negative number zero.
- An explanation of your choice for what to call for input of zero.
2. Write your own unique Python program that has a runtime error. Do not copy the program from your textbook or the Internet. Provide the following.
- The code of your program.
- Output demonstrating the runtime error, including the error message.
- An explanation of the error message.
- An explanation of how to fix the error.
