    Calculating Cauchy's PDF, using domain definition drawings of F_X/Y(z)

    Ok. (Some breakthrough found. All I want is to solve this problem in a way I -- simple student can understand. So your help IS NEEDED.) I complained I don't know P_Z(z<0) & P_Z(z>0). Well I know them, since P_Z=X/Y(z<X/Y<0)=P{X<0,Y>0 U X>0, Y<0}=1/2, I can assume I am able to do something with...

    Calculating Cauchy's PDF, using domain definition drawings of F_X/Y(z)

    Hi, I am trying to draw F (CDF of Cauchy) using X/Y relation for X,Y~N(0,1) iids and at some point very shortly I get lost. Especially because I don't know if I'm on the right direction. Could you direct me to the right way of solving this using the way I chose? So. Problem: Given X,Y~N(0,1)...
