Question

What is ment by the Golden ratio and how can it be calculated?

Answer 1

The Golden ratio is a special number found by dividing a line into two parts so that the longer part divided by the smaller part is also equal to the whole length divided by the longer part. It is often symbolized using phi, after the 21st letter of the Greek alphabet.

Two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.
