I have a problem with my calculations. I have changed the Order to 15. If I go any higher than this I get the error message:
"Error, invalid input: rhs expects 1 argument, but received 0"
after the loop. I need to calculate more terms. Does anyone know why this is happening and how I can fix it?
This is the spreadsheet
Start with the differential equation
Write in a series of powers of R
Extract the individual equations for each power upto R^5
Define the boundary conditions
Solve the boundary value problem for each power

Any help would be much appreciated. Thanks
