Re: Consider two rvs X and Y with joint pdf f(x,y)=k−y, 0<y<x2 <1, find thHi lucik1900; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20130509 03:18:45

Re: Consider two rvs X and Y with joint pdf f(x,y)=k−y, 0<y<x2 <1, find thYes, it is, but I have noticed that people often use that kind of notation when they do not know how to put an exponent in the superscript.
