- Equation that calculates joint rotations in a multi-storey structure

Hi there,

I am going through a book on multi-storey steel structures and I have come to a chapter that gives approximate methods to calculate rotations at the joints (The intersecting members) of a rigid frame. There is a recurrence equation that computes the rotations and this is given below:

The book mentions a few strategies to solve this equation. However, I am finding it quite difficult. The book mentions that you can use iterative methods and that you can start by approximating theta(i) as:

Is there anybody that can help with this, please?

Many thanks.
