The Golden Ratio or phi

Revision as of 11:09, 15 June 2019 by Colball (talk | contribs)

Nobody likes the $\approx$ symbol. They prefer the $=$ symbol or inequalities. However, this symbol is needed when working with Fibonacci numbers. For example the approximation: $F_(n-1)+ \frac{1+\sqrt{5}}{2} /approx F_n$ where F stands for Fibonacci number.
