Noun. mathematical relationship where the ratio of the sum of the numbers (a, b) divided by the larger number (a) is equal to the ratio of the larger number divided by the smaller number (a/b). The golden ratio is about 1.618, and represented by the Greek letter phi, .

## What mathematician discovered the golden ratio?

The first known calculation of the golden ratio as a decimal was given in a letter written in 1597 by Michael Mästlin, at the University of Tübingen, to his former student Kepler. He gives “about 0. 6180340” for the length of the longer segment of a line of length 1 divided in the golden ratio.

**How do you calculate the golden ratio?**

What is golden ratio

- Find the longer segment and label it a.
- Find the shorter segment and label it b.
- Input the values into the formula.
- Take the sum a and b and divide by a.
- Take a divided by b.
- If the proportion is in the golden ratio, it will equal approximately 1.618.
- Use the golden ratio calculator to check your result.

**What is the golden ratio history of math?**

Throughout history, the ratio for length to width of rectangles of 1.61803 39887 49894 84820 has been considered the most pleasing to the eye. This ratio was named the golden ratio by the Greeks. In the world of mathematics, the numeric value is called “phi”, named for the Greek sculptor Phidias.

### Did Fibonacci discover the golden ratio?

Euclid’s ancient ratio had been described by many names over the centuries but was first termed “the Golden Ratio” in the nineteenth century. It is not evident that Fibonacci made any connection between this ratio and the sequence of numbers that he found in the rabbit problem (“Euclid”).

### Why was golden ratio invented?
