The formula for calculating the ratio of golden section point is (√5- 1)/2. The golden section refers to dividing a line segment into two cosets, so that the proportion of one part to the total length is equal to that of the other part. The ratio is an irrational number, and the approximate value of the first three digits is 0.6 18. Because the shape designed according to this ratio is very beautiful, it is called golden section, also called Chinese-foreign ratio.

What is the definition of the golden section?

When a line segment is divided into two parts so that the ratio of the larger part to the total length is equal to the ratio of the smaller part to the larger part, this ratio is the golden section, and its ratio is (√5- 1) to 2, and the approximate value is 0.6 18. Usually, the Greek letter Ф is carefully used to represent this value. Divide a line segment into two parts so that the ratio of one part to the total length is equal to the ratio of the other part to this part.

Its ratio is an irrational number, expressed as a fraction (√5- 1)/2, and the approximate value of its first three digits is 0.6 18. Because the shape designed according to this ratio is very beautiful, it is called the golden section of Lu, also known as the Chinese-foreign ratio. This division point is called the golden section point (the golden section ratio is usually expressed by φ), which is very interesting.

Around the Renaissance, the golden section was introduced to Europe by Arabs and was welcomed by Europeans. They call it the golden method,17th century European mathematicians, and even call it the most valuable algorithm among random tape backup algorithms. This algorithm is called the three-rate method or the rule of three numbers in India, which is what we often say now.
