@janhardo  but something is missing which i want just write the system and then finding fixed point and then do all stuff like eagenvalue eagenvector and and stability stuff  then plot can we have something very clear !, but how find initial condition ?

@nm this lambert make problem for me and it is fixed untill now i hope in future not coming up, if you have any other file related to solving ode and system of ode in maple please upload here becuase i want a full coursebook about this topic or if you have a course book for sollving ode it will be so good if shared with me thank you so much again.

There is any other information about this question?

@mmcdara  we can find that

@acer i think this is the best explanation for mean of best 

@acer i want something automatically search for making best shape of graph it seem is easy for you , can we have something like that?

@acer .................................................

@janhardo  i will asq more questions in future

@janhardo in top code when you try to figure out for two line  is used textplot but in this file (line-with-t-test.mw) you don't use textplot i want do it without textplot in the file tester

@janhardo  if you watch this from the first one 1line , didn't use  textplot he used something else but in your code in two line he used text plot, also why the when i write t=100 is write like 10e3 in graph don't have space place or what? can you do that for 2 line like the first one

line-with-t-test.mw

@janhardo  can you do that for 2 and three

tester.mw

@janhardo this is emazing really is so good the outcome , can we apply for w line or three line too

tester.mw

@janhardo this is so better, somehow i don't know some part but is good but i want display all of this shape with have t variable inside in one graph ? like your code in red written with different colot  ! can we  do that?

@janhardo , in my code is more easier and i want use my information in the file to plot this kind shape involving line with inside each shape have exact amount of t when increase and dicrease and when t=0 it should be at middle , but in your code is at left hand side which is wronge so how i do that ? in your code is write t=0,1,2,3,4... is wronge time is different when is zero is in middle but in plot in  t=5 is in middle must be change this for being true how do that?

@Kitonum this is by adding text and give it the coordinate , but want something automatically, in this code i don't know how they add automatically for each shape i want something more easier like each shape have the t=# when time change like this

dynamic-graph-lump-t=1.2.3.mw

when

vx, vy := -(a^2*alpha*b*beta + alpha*b^3*beta + 2*a*b*beta^2)/(beta*(a^2 + b^2)*b), beta/(a^2 + b^2)
