Phi is the Greek letter which represent the golden number 1.618. Phi is the only number whose square is greater than itself by one, when expressed mathematically
Φ2 = Φ + 1 = 2.618
We can derive the above equation in the following ways.
Φ2 = Φ1+Φ0
Φ3 = Φ2+Φ1
This can be further written as
Φn+2= Φn+1+ Φn
Φn = Φn-1 + Φn-2
Another significant fact about phi is, its the only number whose reciprocal is less than itself by one, which can be expressed as 1/Φ = Φ - 1 = 0.618.
Symbol of phi in upper case is represented as Φ. Symbol of phi in lower case is represented as φ
