#A=1+1/{1+1/[1+1/(1+1/...)]}# by solving it i get both a positive and a negative solution. Why negative?
#A=1+1/{1+1/[1+1/(1+1/{1+1/[1+1/(1+1/...)]})]}#

This is a flash, from my memory.
Explanation:
Here,
There are two A-intercepts,
B = A- ( 1 + 1/A ).
See graph.
graph{y-x+1+1/x=0}
Inversely,
the two branches of the hyperbola have separate equations
The A values under reference are against B = 0.
graph{y-x+1+1/x=0}
The positive intercept is from the branch in #Q_1 and Q_4. The
other is from the opposite branch.
