@janhardo  can you try other question of mine i needed to do for some other ode  i have other one which is so close to this can you find even just one of thus solution satisfy the ode? can you do by your Ai really i needed to satisfy odetest at least for one of them , is similar to this ode but totally different but have a trick

 

 

this idea is so good, but some of them ...

@janhardo  can you try to get thus be zero too becuase i have too make zero all of them  my error is start at here i mentioned in the file , can you undrestand what will happen to this phi  inside function there is must be another idea

thank you so much,......

@mmcdara after spending more than 2 day and changing variable one by one i get the best shape of existence  plot, your trail is so good and design are emazing, i like your style plot but i have a lot of this long function which i have to plot them becuase of that i asked is make me angry when i spen this time for one plot

@dharr  is so better than before becuase i have a lot of that U(xi) i am looking for them but this index work very good thanks

@acer it pretty working with this kind of factoring it do all factoring this is so good and i like it, i try to use both of your code to see which one is better the factoring is better work because the other code make fraction

@acer  the idea a little bit long i am not answer becuase i changed my problem, i have to work on your code really is so pretty and i have to apply for my equation all of them i will work on it after finishing my work on equation i will back to this pretty code you write and if i stuck for another question like that i will ask to help again , please give me a little time to solve my equation, and this code you write it is remove a lot of comment of reviewer of journals  i copy and paste the equation from maple to latex and if they don't so compact they will mention why you didn't do that and this process will make my paper to get revision i don't want my paper get revision and accepted at once.

thank you so much...

i want plot that with make a generation parameter specialy when we do G(k,a,b,c,d,f,epsilon) in my function we have that i want to plot 2@D and 3D  but we generation parameter each time for one graph for example in first time we have G(k,1,b,c,d,e,l,epsilon)&G(k,0.5,b,c,d,e,l,epsilon)&G(k,0.2,b,c,d,e,l,epsilon) be like that also all b,c,d,e,epsilon are random parameter and k is range , i want something easy to undrestand and effective like this
