Question: differential transform method (DTM)


I have an equation which i want solve it with DTM, but there are two problems:

1- How do I write a Dirak Delta function in maple for this equation?

2- I used pade approximation due to initial condition. Then how many sentenceses should be used to achieve the correct answer?

in this equation there are some constant parameter.

M:=0;A:=1;Phi:=0;r:=0.5;lambda:=0;phi[1] := 1.;  beta := .67;   phi[1] := 1.



That's my pleasure If there is somebody help me to code and solve this problem.

Thanks for every one very very much.
