Please explain every detail, I know it is the derivative but I feel I am missing a step because they obtain some kind of constant with it Problem: CDF= 0 x less than or equal to zero x/4*(1+ln(4/x)) 04 Solution PDF is obtained by differentiating the CDF function so for x<0, PDF(x)=0 for 04 PDF(x)=0.

1. Please explain every detail, I know it is the derivative but I feel I am missing a step because they
obtain some kind of constant with it
Problem:
CDF=
0 x less than or equal to zero
x/4*(1+ln(4/x)) 04
Solution
PDF is obtained by differentiating the CDF function so for x<0, PDF(x)=0 for 04
PDF(x)=0
