Dear @mmcdara @tomleslie

Is this possible to add contour labels to the graph?

Tim Leslie 7597 suggested the above-mentioned link, there it is explained for algebraic functions only.

In this case, we have the data in the matrix form.

Kindly help me to shoot out this problem.

Dear @tomleslie

Thanks for your reply.

Is this possible to add the contour sequence and how to incorporate the labels in the graph?

Dear @tomleslie

Please find this attachment.

This paper problem only I am trying to get a solution.

Paper: perturbation.pdf

In this paper, equations 14-16 are solved using the perturbation function 20a-20e with the help of 17a, 17b and 18.

After applying the boundary condition and perturbation function in equations 14-16, they displayed the final form in equations 21-23.

Dear @tomleslie @Carl Love

I have tried the below-mentioned problem. But the outcomes are not matching. I don't know where the mistakes happen.

Equation:

Condition:

perturbation expansion:

Is there any possibility to get a solution to this problem?

Waiting for your reply.

Dear @tomleslie

Thanks for your notable support.

The outcome looking nice.

Dear maple users,

I hope anyone of the users answers this question.
