Study Notes
Overview of Mathematics
- Definition: The study of numbers, quantities, shapes, and patterns.
-
Branches:
- Arithmetic: Basic operations (addition, subtraction, multiplication, division).
- Algebra: Study of symbols and rules for manipulating those symbols; includes solving equations.
- Geometry: Study of shapes, sizes, and properties of space; involves points, lines, angles, surfaces, and solids.
- Trigonometry: Study of relationships between angles and sides in triangles; key functions: sine, cosine, tangent.
- Calculus: Study of change and motion; includes differentiation (rates of change) and integration (accumulation of quantities).
- Statistics: Study of data collection, analysis, interpretation, presentation, and organization.
- Probability: Study of uncertainty and the likelihood of events occurring.
