Question

6.00 Fall 2008
In problem set 1a (ps1a), should I just print the prime number or print all the steps of the generate-and-test method?
Also, in Ps1b, I really don't understand the math behind it ...I googled it and found out what a log is (don't mock..I'm 'very' young..I think I'll study (log) next year at school)
What does the "e" represent in "e**n" ?? Much help needed :D
Third and Final question, should I switch to 6.00 spring 2011??
Thanks in advance :)

Answer 1

1. imprimes todos hasta el numero n que escribas: example
n=7
prime(n)= 2,3,5,7

2. if is_prime(n)
cont=cont+log(n) cont is a accumulator

log is the exponent to which the base must be raised to obtain the number

\[3^{2}=9 \rightarrow \log_{3} 9=2 \]

Answer 2

e is the base for natural logarithms natural logs turn up frequently in calcs for real world phenomena http://en.wikipedia.org/wiki/E_(mathematical_constant) http://en.wikipedia.org/wiki/Natural_logarithm

i took the 2008 course b4 the 2011 course was offered. when i look at the psets for the 2011 course, they look very similar except they seem to be in a different order. i learned a lot in the 2008 course

Answer 3

@NanZY you can use the function `log()` (return a log of a number) without knowing what it is.
But remember add `from math import *` at the beginning of your code, so you'll be able to use it later
Good luck

Answer 4

import math

math.log(x)

Answer 5

Thank you for caring to answer :)
I'm still trying to figure it out x(
A bit disappointed though...
never thought it would be that hard...
:) Thanks again ;)
