So I'm given a non-linear equation, and I want to solve for u2 but I don't know the value of A. L=R=1 is given. And it says to use fsolve, but I can't get it to work unless I just give a value for A. Can I get some assistance, thanks!

"A" must also be given if you want to use "fsolve".

http://www.maths.adelaide.edu.au/matthew.roughan/notes/Variational_methods/files/lecture16.pdf On here pages 24-35 describes the problem that needs to be solve numerically. And it says to find A later on. To find u2 using that equation.

No it does not. It defines A above that point. It says that all you need to know is u1 which gives you A and then you can calculate the others. u1 is a boundary point it appears.

Don't know u_1 either, thats to be found later.

"Minimum occurs for u_1 = 1, we’ll prove this later on."
