@C_R 

Thanks.

yes, I want to see whether the error for a given n is acceptable or not.

@NIMA112 

Thanks again. In the calculation process, I selected (num=35). How can I detect the maximum value of num to be sure the series solution would converge?

@C_R 

Thanks so much

@C_R 

Thanks so much.

Yes, GG[11]  is the product of A*B*C, where B in the middle is a sum.

Could you please update your idea in this regard?

Best

@mmcdara 

Do you check boundary conditions in the attachment pdf file? 

Can I use them in  FreeFEM?

Thanks

@mmcdara 

Thanks so much.

Please see the attachment (example6.2) for all of the boundary conditions.

I want to solve this example through other possible analytic or numerical methods.

@acer 

Thanks for your guidance .

could you please help me for runnig code on maple 2020?

I have encountered with this error"

Error, invalid input: seq received numelems, which is not valid for its 2nd argument, i

Error, attempting to assign to `numelems` which is protected.  Try declaring `local numelems`; see ?protect for details.

@acer 

Thanks so much, dear Acer,

I have changed the code to plot other parameters but it seems there is another important point to do this. Please take a look at the file I've attached and let me know about any necessary corrections about this.
