The Unexpected Solution

**[y_=_x_+_1]**
**[y_=_x_*_x]**
**[Phi_=_1.618...]**
**[Phi_=_-0.618?]**

**[Derive_Phi_Graphically]**

## Phi = -0.618?...

**Where did this come from?**

Despite the oddity of this '**~phi**', if you consider the rectangle
formed by the **blue lines**,
the **x axis**, and the **y axis**, you'll see it's a Golden Rectangle with sides
of **~phi** (horizontally) and both **~phi * ~phi** and **~phi + 1**
(vertically).
