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 parts so that the ratio of one part to the total length is equal to the ratio of the other part to this 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, which is usually expressed by the Greek letter Ф. 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 golden section, also called Chinese-foreign ratio. This dividing point is called the golden section point (the golden section ratio is usually expressed by φ), which is a very interesting number.
