1. Homework Statement
Here is the link to the old thread, https://www.physicsforums.com/showthread.php?t=349730
i tried posting but it doesn't seem active. I don't understand how they get the second pdf as i tried it and got the first pdf. I also don't know how to do the double integral as what would the limits be?
2. Homework Equations
2. Homework Equations
Limits for checking pdf
Pdf itself
3. The Attempt at a Solution
i got the same as rosh300 in the first attempt.
Any help would be appreciated
f_(r,theta)={1.5(r^2)/pi, for r E [0,1] and theta E [0,2pi]??
0 otherwise
by doing the double integral formula this gives 1 as required. However i don't know how to find the marginal distributions of X and Y
