If you use pencil, do not erase anything. If there are erasures, you get zero points. This question assumes spherical coordinates. Consider the following function , which only depends on the distance from the origin, r: u( r ) = Ae− r + Ber Cr l +1 + Dr − l Assume that l is a positive integer. ( )( ) 1. You want to make sure that this function does not “blow up” as r goes to infinity. Which coefficient must you set equal to zero? A B C D 2. You also want to make sure it does not “blow up” as r goes to zero. Which coefficient must you set equal to zero? A B C D 3. Write down the resultant function. Is it well‐behaved, even if l=0? ...
