@Carl Love Thanks for cooperation and suggestion, could please guide me about that problem , how to solve with BVP solver rather than shoot. i am not familiar with BVP solver. thanks 

@sharena2 Thanks for your reply . ya i have two different function differentiated in one differential equation, so could you please guide me how  can i resolve this issue. Second if possible can you upload the corrected form of your above mentioned question. May be it can help me more to understand. Thanks 

@Carl Love  ya i got it . thankyou for your nice suggestion and cooperation

@sharena , hi , i am facing same type of error , can you tell me how you remove this error . I am waiting for your nice reply . thanks 

@Carl Love Dear Sir , can you tell me what would be the command to calculate the critical value of lambda for above problem  when f0=0, n=0, Pr=0.5 . For information calculated critical value for lambda is -0.0594.  Just i want to know how can i calculate it. thanks  

@Carl Love  i am sorry .Actaully i was totally stuck thats why it happen. Thanks alot for your consideration and cooperation

@Carl Love Dear Sir, i am sorry to ask you again  that i am not asking to combine the graph for different function. 

I am asking to combine a graph at different values of parameter i.e n=0, 0.1, 0.2 for same function f'.

In above sms , i try to explain all the thing that i did to draw combine graph for single function in the view of you instruction i.e. plots:-display

Thanks for cooperation.

@Carl Love Dear sir for sigle graph i use this command 

p1 := odeplot(S, [eta, u(eta)], 0 .. 10)

display(p1)        

where f'=u, using above command i can draw single graph at any value for n but when i wish to draw combine at different value of n fail.

According to your instruction given in above sms as "plots:-display" ,  I  used is such a way for n=0, 0.01,0.02;

p1 := odeplot(S, [eta, u(eta)], 0 .. 10)  

plots:-display(p1)  

but still got single graph at n=0 , but when i putted command in such a way 

p1 := odeplots(S, [eta, u(eta)], 0 .. 10)

plots:-display(p1)

i got following error 

Error, (in plots:-display) expecting plot structure but received: odeplots(S, [eta, u(eta)], 0 .. 10). 

Dear sir , suggest me what should i do now to get combine graph for sigle function at different values of parameter. thanks 

@Carl Love Dear sir  thanks for your attention and cooperatrion. 

@Markiyan Hirnyk Dear sir, here is detail p'=lambda*theta   and  eta is independent variable  i.e mean for above equation prime shows derivative with respect to eta 

@Carl Love 

Dear sir  here is detail , kindly see and sugest me to resolve it

for example we have following equation f'''+n+1/2ff''-nf'^2-2np-n-1/2 eta p'=0, where p'=lambda*theta and for whole equation,  prime shows derivative with respect to eta .  Now how can i draw  combine graph for velocity profile f' at n=0, 0.01, 0.02 using shooting method . Single graph of f' at n=0 or at any other valu of n , I can draw but i donot know the command for combine graph at different values of n for velocity profile .  I am waiting for your nice reply.Thanks.
