Differential equation is given as dx2d2u−x=1u(0)=0u(1)=1 And the trial functions are N1(x)=x2−xN2(x)=x3−x By using the Galerkin's method of weighted residuals and the specified trial functions, determine: i) one-term approximate solution ii) two-term approximate solution iii) how can we improve the accuracy?
