hi, I want calculate lambda(lagrange multiplier) for lane emden type equation, I have made a programme for it but here is error at the end of programme,plz help

lambda.3rd.mw

hi, I am tyying to solve this equation but there is arising an error, plz help me,
VIM.3rd_order.mw

Hi, I'm tying to solve the ODE by variational iteration method, programme is running, but maple answer does'nt  match to origional answer, plz tell me the mistake?

ICs y(0)=y'(0)=y''(0)=1

VIM_2.mw

 

diff(y(x), x, x)+2*(diff(y(x), x))/x+af(x)*g(y(x))=0

restart

"n:=5:  y[0]:=0:  f(x):=1:  g(y):=e^(-y): L:=x^(-2)(ⅆ)/(ⅆ x) (x^(2)(ⅆ)/(ⅆ x) ):  L^(-1)(y):=(∫)[0]^(x)x^(-2)(∫)[0]^(x)x^(2)dxdx:  "

"for m from 1 to n do:  `&varkappa;`[m]:={[[0,m<=1],[1,m>1]]:   R[m]:=simplifyL^(-1)((d^(2)y[m-1])/(dx^(2))+(2)/(x)(&DifferentialD;y[m-1])/(&DifferentialD; x)+f(x)g(y) );  y[m]:=simplify(y[m-1]*`&varkappa;`[m]-R[m]):  od;"
