i am asked to find the greens function for
with u(0)=0 and x>=0
i found the homogenous solution and used the 4 conditions...
my homogen soln was u=constant * exp(-kU)....
is it possible that my G(x,s)= 0 for x<s and X>s?
also how do i show that -u"= f(x) is not self adjoint with bc
u(0)=0 and u'(0) +u(1)=0
i have the greens function but the bc's dont hold for it?
is that right?
