lambarada Fibonacci

lambarada Fibonacci waa tirooyin taxane ah oo ka bilaabma tirooyinka 0 iyo 1, qiime kasta oo xigaa waa wadarta labadii hore.

Foomamka Taxanaha Fibonacci

Tusaale ahaan:

• F₀ = 0
• F₁ = 1
• F₂ =F₁+F₀ = 1+0 = 1
• F₃ =F₂+F₁ = 1+1 = 2
• F₄ =F₃+F₂ = 2+1 = 3
• F₅ =F₄+F₃ = 3+2 = 5

Qaybta Dahabka

Saamiga laba nambar oo Fibonacci oo isku xigta ayaa isku biiraya saamiga dahabiga ah:

halkaas oo φ waa saamiga dahabiga ah = (1 + √5) / 2 ≈ 1,61803399

Inta badan, qiimahan waxaa lagu soo koobaa ilaa 1,618 (ama 1,62). Boqolkiiba la soo koobay, saamigu wuxuu u eg yahay sidan: 62% iyo 38%.
