For the functional J[u]= ( [u+uy +(x*+y#)u]dxdy 2 2. Find Euler -Lagrange eguation. The eguation which you found solve within this region: 1 In figure bound ary the above conditions are given. As approximate Solution take an u= Axy (1- x-y) This function Satis fies boundary Condition. Find A by minimiding functional. For the functional J[u]= ( [u+uy +(x*+y#)u]dxdy 2 2.
