@Carl Love 

Will it be fixed later?

 

No, I just wanted to enter in the attached program instead of definition.

@Carl Love 

If you intended the tanh question to be independent of the error, I can attempt to answer it.

Okey

Your pde2 is not explicitly an equation because it doesn't consist of two expressions separated by =

It is the same image above the program. I wrote wrong?

@Carl Love 

it is the Partial differential equation that becomes an ordinary differential equation in the second step.

What is wrong with the attached program?...

Yes, I checked and understood the first part.

 

But I didn't understand the second part, that is, I know what you did until the green part.

@mmcdara 

I want to solve equation 3-4. For this, we assume that we have the equation 2-9 where the values of m = n = 3. Then the answers to 3-5 and 3-6 are obtained. But it does not happen in practice???

Why didn't you consider the first two terms?
