thank you
I really appreciate it

if you dont mind, i have 1 more question..

how if i want to know, how many Eulerian circuit of the graph and what trajectory?

thanks a lot..

i've tried it..

but still like this

do you have any other command to make the graph into a form that I want??

share it, if you have...

thank you so much for your help...

may i ask you 1 more question..

if i have

(x^n+epsilon*y(x))*y'(x)+n*x^(n-1)*y(x) = m*x^(m-1), y(1) = b>1

where n=2,3,4,.. and m=0,1,2,3,..

how to solve that???

thank for the answer

but why when i entry sol1..

it's error..

when i entry sol1, the output is

> sol1 := dsolve({(x^n+epsilon*y(x))*y'(x)+n*x^(n-1)*y(x) = m*x^(m-1), y(1) = b}, numeric, parameters = [n, m, b, epsilon]);
%;
Error, (in dsolve/numeric/an_args/SC) keyword was parameters, optional keyword must be one of 'range', 'abserr', 'relerr', 'initstep', 'maxfun', 'initial', 'steppast', 'output', 'procedure', 'procvars', 'start', 'number', 'startinit', 'implicit', 'interpolate', 'stop_cond', 'optimize', 'complex'

thank for the answer...

you have a different answer than the previous... i have another questions too..

what is the use of the command Y_vals??

i have the exact solution used HPM of the equation

y=-x/b + 1/b √(b^2 + 2b + x^2)

how if i want to compare it with numeric solution??

thanks again for the answer..

thank for the answer...i have another questions..

what is the use of these commands??

so if I want to work on another example, I know from where I should start...
