One must be careful in general cause a PDF doesn't always exist, but here taking this derivative will do the trick. (The discontinuity across the line x = 1 isn't a big deal. The support of the PDF just drops suddenly to zero when you cross into the half plane x > 1 .) Share blue tufted mirror dresser wayfair
