## defaults...

@Carl Love sir, what about if we want to calculate n from 20 to 30? as you mention it started from 1 that is by default.

## range...

@Preben Alsholm thanks sir, I am interested in n from 1 to 11 ....is the above is the same thing?

## try...

@tomleslie sir I tried but was thinking maybe I am doing anything wrong

## Thanks...

@Kitonum it is working accordingly thanks alot

## derivative...

@Kitonum Dear sir, i already find the solution by using fsolve and newton method but i am interested to find to by using Regula falsi method, pls correct me where is the problem, why it is not giving result. By the wan can you explain why you take derivative of the P?

## Rf...

@Carl Love Dear sir, i already find the solution by using fsolve and newton method but i am interested to find to by using Regula falsi method, pls correct me where is the problem, why it is not giving result. By the wan can you explain this command why you did this, what does it means?

`d:= ilog10(op(1,r));`

## need expression or polynomial...

@Preben Alsholm sir basically i need an expression in terms of sigma when pg1=0 to use in another expression so that is why I am using fsolve or considering numeric values or we should construct a polynomial of an expression fter obtaining pg1=0 for different value of k and q, but the problem is  how to construct a polynomial for sigma in term of lamda for fix value of k and Q by using fitting curve command....sorry i am no to good in maple

## need expression...

@Kitonum sir basically i need an expression in terms of sigma when pg1=0 to use in another expression so that is why I am using fsolve or considering numeric values

## @Preben Alsholm  it is working only...

@Preben Alsholm  it is working only when n=1 but could not get the answer when n greater then 1

@Preben Alsholm sir can you pls did the same thing in my worksheet that i already attached because i am applying this command but could not getting the answer

## plot...

@tomleslie Thank you for our time and is there any option to convert original ODE Into a set of the first-order ode by using commands and how to plot the final result if the value of epsilon in numerator A and in denominator  =B for different value of  A and B.

sir one more thing how can i apply perturbation method on the same problem?

## @Carl Love yes, you are write ...

@Carl Love yes, you are write  the original Equation is 2d order ode. as now i want to calculate the value of both involved constant of integration that is A and C1 by using the given both boudary condition

## Thanks...

@vv with due respect we already follow the same procedure to draw these type of graph and we call this graph streamline graph and they have alot sense to us. i just change the basic equation to draw but faceing issue

## complete file...

@acer dear sir please a complete file, actually i want to plot  please have a look on my file

complete.mw

## Example...

@vv sir please a look on attached file. I need an expression like in attached file......in this file v is also a function of both x and y

Example_Int.mw
