if we use the boundary condition at r=0, a = 0, for the following equation

a = C1r + C2/r + qr

is it safe to say that C2=0? and thus:

a = C1r + qr

what do you mean by unbounded sorry?

If you sub in a = 0 and r = 0, you are left with

0 = C2/0

however this make no sence because dividing by 0 should give infinity - May 12th 2010, 07:32 AMJester
