@tomleslie 

A friend of mine, asked me this question.
I'm not familiar with MOL.

I thinck because of the symmetry condition,  interval of time and space is divided into 10 parts(delta t =0.1).

Thank you very much

@Markiyan Hirnyk 

thank you

 But the curves should be drawn that it does not in principle.

Each curve has a maximum point,we must connect the dots together.

@Axel Vogt 

thank you very much

@Kitonum 

thanks

but in my book these curves are round(not line and not  in negative zone)???

@Kitonum 

with right click on diagram --->  Axes  ---> create second Axis

then click on red curve ---> Axes ---> move second Axis

@gkokovidis 

Your advice was very helpful

thank you very much.

@Kitonum 

thank you very much

@Kitonum 

thank you

but my teacher solve this with runge kutta method with maple and curves have intersection point???

@nm 

sorry 

I did a mistake in typing formula

The correct formula is as follows:

y''+(4/x)*y'-ay^n=0

and a=constant

@Carl Love
