Question
1- Given the ordinary differential equation
e" = x
in 0<x < 1
with boundary conditions
9(0) = 1,
O' (1) + 30(1) = 0
(3
is a given constant)
By assuming a polynomial of the form
N+1
:=0
(a) Deduce a general form for trial functions satisfying the boundary con-
ditions
(b) Apply a one-term collocation method to obtain an approximate solution
(c) Apply Galerkin's method to obtain an approximate one-term solution
(d) Repeat parts (b) and (c) by taking two-terms.
(e) Evaluate the approximations at least at four different points and com-
5
pare the results by assuming 3 = G)
(f) Plot the approximations on a millimetric graph paper and also display the
exact solution.
