PageIntroductionMy article is about the golden ratio. I chose this topic because I had never heard of it before and because it seemed fun. My main question for this research is: "What can you use the golden ratio for?" My sub-questions are: 1. How did they arrive at the Golden Ratio?2. What is the most important function of the Golden Ratio?3. How can you correctly use the golden ratio to show that it is a fixed number and which one?4. Can you find examples of the golden ratio in everyday life?The golden ratio. “Divina Proportia” which means divine proportion. Also abbreviated by the Greek letter: (PHI). It looks a bit like the number π. Π Gives the ratio of the diameter of a circle to the circumference of the circle, which has a value of 3.14. Very similar to π in this sense, it also indicates a ratio. Only then, a line segment report. Just like π, it also has a fixed number. Or should I say two fixed numbers. Positive:  1.61803398875 or negative:  0.61803398875. The positive number is the “Official” number, and the negative number is the subject of many doubts. Many say it has something to do with it, but not really in the middle of the paper series......nnaci and are shared by each other nearby. If you look even more specifically, you'll see that (usually) 5 goes clockwise and 8 goes counterclockwise. These numbers also follow one another in the Fibonnaci series! And that's not the only thing in the sunflower that has to do with the golden ratio. Like most plants, sunflower leaves form spirals. Not as many in one place and not in one round. But in different places and in several turns. These are (almost) always the same as in the Fibonnaci series. So, for example, 2 sheets for 1 round (1/2) or 8 sheets for 3 rounds (3/8). There are many examples of the golden ratio in everyday life, but to list them all I would have to use 3. write pages. So there will be some new things in thinking about this research, but it is now ready for research eleven.
