Thanks for your kind replies

I need an asymptotic series in general which contains S0, because S0 in my actuall analysis is the postion of a phase change problem. which changes after time to time. Thats why I need a general form. I have numerical results for it, but I am interested in asymptotic. 

My main equation which conatin the discuss part (which we now are playing with to get asymptotic series) is 

 a:=-variphi*sigma+Ste1/S0*sqrt(l^2+sigma)*coth(sqrt(l^2+sigma)*S0)+R1*R4*Ste2/(1-S0)*sqrt(l^2+sigma/R4)*coth(sqrt(l^2+sigma/R4)*(1-S0))-l*R3*(1-R1)*coth(l*S0)-((1-R1)*(variphi*sigma+R3*l*coth(l*S0))*(coth(l*S0)-coth(l))*cosh(l*S0))/(R1*R2*(sinh(l*S0)-cosh(l*S0)*coth(l))-coth(l*S0)*cosh(l*S0)+cosh(l*S0)*coth(l))=0;

For the above equation i need asymptotic series.

Thanks

Thanks once again

If I suppose that S0 belong to (0 1) then is it possible that i will get an asmptotic series in terms of S0.

Thanks for your very very quick responce. I already tried to convert it first to exp form and then I applied asympt but I face the same problem.

Actually I need it in general form. I dont want to give a specific value of S0.

If you have some other idea please let me know.

Thanks

One thing more can i generate four plots at a time from this code which you send me

Hi,

I try to upload but it doesn't work. now I am sending you the procedure which I use.

Thanks for your time
