The golden mean is the number
\tagmcend
\tagstructend
\[\frac{1 + \sqrt{5}}{2},\]
\tagstructbegin{tag=P}
\tagmcbegin{tag=P}
that is, the root larger in modulus of
\tagmcend
\tagstructend
\begin{equation} x^2 - x - 1. \end{equation}
\tagstructbegin{tag=P}
\tagmcbegin{tag=P}
It is usually defined as the ratio of two lengths \auxiliaryspace
\tagmcend
\tagstructend
\(a\)
\tagstructbegin{tag=P}
\tagmcbegin{tag=P}
and \auxiliaryspace
\tagmcend
\tagstructend
\(b\)
\tagstructbegin{tag=P}
\tagmcbegin{tag=P}
such that
\tagmcend
\tagstructend
\begin{equation*} (a+b) : a = a : b. \end{equation*}
\tagstructbegin{tag=P}
\tagmcbegin{tag=P}
Let \auxiliaryspace
\tagmcend
\tagstructend
\(x\)
\tagstructbegin{tag=P}
\tagmcbegin{tag=P}
be the ratio \auxiliaryspace
\tagmcend
\tagstructend
\( \frac{a}{b} \).
\tagstructbegin{tag=P}
\tagmcbegin{tag=P}
We have \auxiliaryspace
\tagmcend
\tagstructend
\( \frac{a+b}{a} = 1 + \frac{1}{x} \),
\tagstructbegin{tag=P}
\tagmcbegin{tag=P}
from which we get the equation \auxiliaryspace
\tagmcend
\tagstructend
\(x^2 = x + 1\).
