Paper

Hello. I'm reading the above paper and I do not understand how they managed to solve eq (17.35) -- i've seen many papers skip through this as trivial and didn't bother to show the method to get there.

I would be grateful is someone could explain the steps from get to the solution given.

Many thanks.

  • $\begingroup$ Perhaps this is where I am going wrong....does the minimisation of the cost give n = h^2? $\endgroup$ – user39367 Mar 24 at 18:20

I used Latex to write out the process:
