Study Notes

Sequences and Series

  • Arithmetic Sequence: Consists of terms with a constant difference; for example, a sequence like 5, 10, 15, 20 increases by 5.
  • Geometric Sequence: Each term is derived by multiplying the preceding term by a fixed number; an example is 2, 4, 8, 16, where each term is multiplied by 2.
  • Fibonacci Sequence: Each number is the sum of the two preceding numbers, starting typically with 1, 1, leading to 2, 3, 5, and beyond.
  • Harmonic Sequence: Composed of terms whose reciprocals form an arithmetic sequence.
  • Triangular Numbers: Formed by arranging dots to create an equilateral triangle; examples include 1, 3, 6, 10.

Mathematical Concepts

  • Golden Ratio: An irrational number approximately 1.618, prominent in nature, aesthetics, and architecture.
  • Symmetry: Indicates that an object remains unchanged under transformations such as reflection or rotation, highlighting balance in design.
  • Tessellation: Involves packing shapes tightly without gaps; a natural example is the honeycomb structure of beehives.
  • Pascal's Triangle: A triangular array showcasing binomial coefficients, useful in probability and algebraic expansions.

Geometric and Natural Patterns

  • Fractal: A geometric shape exhibiting self-similarity, where smaller sections mirror the entire structure.
  • Self-Similarity: A defining characteristic of fractals; any portion resembles the overall shape.
  • Fractal Tree: Represents a natural fractal pattern, where smaller branches branch off from larger ones, demonstrating growth and pattern consistency.
  • Geodesic Sphere: A spherical structure composed of interconnected triangles, as observed in soap bubbles.

Growth Patterns

  • Exponential Growth: Describes a scenario where quantities grow rapidly at a constant rate relative to their current size; frequently modeled by geometric sequences.
  • Exponential Decay: Involves a rapid decrease of quantities at a constant rate, exemplified in phenomena like radioactive decay.

Triangle and Geometry

  • Isosceles Right Triangle: A specific triangle type with two equal-length sides and one right angle, foundational in trigonometric principles.
  • Euclidean Geometry: The study of flat space and shapes, forming the basis of classical geometry involving entities such as circles and squares.

Natural and Mathematical Patterns

  • Minimizing Surface Tension: A principle in nature observable in the formation of water droplets and cloud shapes, influencing how structures stabilize.
  • Logarithmic Spiral: A spiral pattern that enlarges as it circles, commonly found in natural forms like galaxies and seashells.
  • Pythagoras: An influential ancient Greek mathematician emphasizing the significance of numbers, laying groundwork for mathematical exploration and structural patterns.
