show step
solve the Sturm Liouville problem
Y"+hY=0,
NB: h means lambda
y(0)+y'(0)=0
y(1)+3y'(1)=0
obleck plz explain better again or damon can you help
so what part did you not get?
You know that if
y = sin(kx)
y" = -k^2 sin(kx)
same for cosine, so any linear combination of the two (c12,c2) is also a solution.
Then plug in the given points to find c1 and c2.
