Apologies for being rusty..
I was recently looking at the calculation of yield to maturity for bonds and was wondering why people in the industry resort to a trial error approach when calculating them.
The YTM calculations boil down to equations like these, where
i is the YTM
So my specific question is
1) Can the above equation be re-arranged to a form
i = ...where I can calculate the right side numerically?
and my general question would be
2) Can't all equations with a single unknown be transformed into
i = ...?
