Finite Elements

A simple partial differential equation (PDE) with boundary conditions is examined:d/dx( x dy/dx ) = xy(0) = y(1) = 0.Integrate the PDE twice to get its solution. Then apply the boundary conditions and get a contradiction. The boundary value problem(BVP)has no solution.Regardless, apply the finite...
