Study Notes
Fundamental Concepts
- Mathematics is a science studying numbers, shapes, and symbols.
- It uses logic and reasoning to solve problems.
- Branches include arithmetic, algebra, geometry, calculus, and more.
Arithmetic
- Arithmetic studies numbers.
- Operations include addition, subtraction, multiplication, and division.
Algebra
- Algebra uses symbols for unknown values.
- It uses equations and formulas to solve variable problems.
Geometry
- Geometry deals with shapes and properties.
- Topics include lines, angles, triangles, circles, and polygons.
Calculus
- Calculus studies continuous change.
- Branches are differential (rates of change) and integral (accumulation).
Set Theory
- A set is a collection of distinct objects.
- Set theory defines operations like union, intersection, and complement.
Number Systems
- Natural numbers: (1, 2, 3,...)
- Whole numbers: (0, 1, 2, 3,...)
- Integers: (...-3, -2, -1, 0, 1, 2, 3,...)
- Rational numbers: expressible as p/q (p & q integers, q ≠0).
- Irrational numbers: cannot be fractions (π, √2).
- Real numbers: all rational and irrational numbers.
- Complex numbers: include imaginary numbers.
Logic in Mathematics
- Mathematical proofs use deductive reasoning from axioms and theorems.
- Logic validates mathematical statements.
Applications of Maths
- Mathematics is used in physics, engineering, computer science, and economics.
- It models and analyzes real-world phenomena.
- Essential for financial modelling, engineering, and problem-solving.
Mathematical Modeling
- Mathematical models represent real-world systems.
- Models predict, test hypotheses, and understand system behavior.
- Models use equations, formulas, and figures to represent systems simply.
Problem-Solving Strategies
- Identify the problem.
- Plan the solution.
- Execute the plan.
- Evaluate the results.
- Problem-solving often uses patterns, relationships, and logic.
Important Mathematical Constants
- Pi (Ï€): Ratio of a circle's circumference to diameter (approximately 3.14159).
- Euler's number (e): A constant appearing in calculus and other areas (approximately 2.71828).
