I don’t know is it my solution was something wrong or not. When I substitute other variables to Fλ1, the answer is a square root of a negative number

Is it a trick question? The two don't seem to intersect for \(\displaystyle x,y \in \mathbb{R}\)

maybe no, it is an assignment question

Actually, they do intersect. Did you look only at the top part of the cone?



@lldk: Your F_z is wrong!

It seems that you are saying that since it is an assignment that even if two do not intersect that it can be done. If in fact they do not intersect then this problem can't be done. However they do intersect and the problem can be done.
