    Hello

    I am new to this forum, but I hope I can get help with a problem I haven't been able to figure out what to do with.

    info:

    we have a one dimensional equation -d/dx [a(x) du/dx] = p(x)

    where we seek a solution u(x) where x is within [0,1] , that satisfies the 2 boundary conditions u(0) = 0, u(1) = 0

    p and a is given by a(x) = 1 and p(x) = 1

    any help with this problem would be very nice. On beforehand thanks

      It's easy. You can find a general expression for u. Since there are two derivatives, it will have two integration constants in it. You then impose those boundary conditions to find those integration constants.
