Study Notes
Fibonacci Numbers & the Golden Ratio
- Mathematics is about understanding patterns and relationships, not just solving problems.
- Learning objectives include articulating sequences, understanding Fibonacci's contributions, and exploring the relationship between Fibonacci numbers and the Golden Ratio.
Sequences and Recurrence Relation
- A sequence is a function mapping integers to a set of values, denoted as (a_n).
- Recurrence relations define sequences based on previous terms; the simplest form depends on just the immediately preceding term.
- Example: If (a_1 = 1), (a_2 = 3), and (a_n = a_{n-1} - a_{n-3}), compute (a_5).
Arithmetic and Geometric Sequences
- Arithmetic sequences have a constant difference between terms. Formula: (a_n = m n + a_1).
- Example of arithmetic progression: 3, 8, 13, 18, 23, 28...
- Geometric sequences have a constant ratio between subsequent terms. Example: (a_1 = 10), (a_2 = 30) where (a_n = 10 \cdot 3^{n-1}).
Fibonacci Numbers
- Leonardo Pisano (Fibonacci) was born in Pisa, Italy, in 1175 AD and educated under the Moors.
- He introduced the Hindu-Arabic number system to Europe, replacing the Roman numeral system.
- The Fibonacci sequence begins with 0 and 1, with each next number found by adding the two previous ones: (F_n = F_{n-1} + F_{n-2}).
Fibonacci Rabbit Problem
- The problem illustrates exponential growth in a rabbit population, where each female produces a new pair of rabbits every month after reaching maturity.
- The key question raised is how many pairs exist after one year.
Fibonacci Numbers in Nature
- The Fibonacci sequence appears frequently in biology, such as in the arrangement of leaves, branching in trees, and fruit sprouts.
Golden Ratio
- The Golden Ratio ((\phi)) is defined as the ratio between two quantities, equal to the ratio of their sum to the larger quantity.
- A golden rectangle has a longer side to shorter side ratio of (\phi).
- Golden spirals are logarithmic spirals that grow wider by a factor of (\phi) every quarter turn, illustrating aesthetic proportions in art and nature.
