The study of many special formations can be done using special sequences like the Fibonacci sequence and attributes like the golden ratio.
The golden ratio, which is also referred to as the golden mean, divine proportion, or golden section, exists between two quantities if their ratio is equal to the ratio of their sum to the larger quantity between the two. With reference to this definition, if we divide a line into two parts, the parts will be in the golden ratio if:
The ratio of the length of the longer part, say "a" to the length of the shorter part, say "b" is equal to the ratio of their sum " (a + b)" to the longer length.
that is, a/b = (a+b) / b = 1.618033.....
You can use the Golden Ratio Calculator which is an online tool that helps to find the golden ratio for the given one number of the ratio.
