Finding the exact phi (φ), or golden ratio, value on a calculator often involves a specific calculation rather than a dedicated function. Here's how:
As demonstrated in the reference video, one way to approximate phi (φ) using a calculator involves iterative calculations:
- Start with the number
1
. - Divide
1
by the current number. - Add
1
to the result. - Repeat steps 2 and 3.
This iterative process will converge towards the golden ratio, approximately 1.618.
Alternatively, you can directly calculate it using the formula:
φ = (1 + √5) / 2
Here's how to do it on most calculators:
- Find the square root of 5 (√5).
- Add 1 to the result.
- Divide the result by 2.
Example:
- √5 ≈ 2.236
- 2.236 + 1 = 3.236
- 3.236 / 2 = 1.618
Therefore, φ ≈ 1.618
While some advanced calculators might have a built-in constant for phi, the above methods are universally applicable.
