Study Notes
Key Concepts in Mathematics
1. Branches of Mathematics
- Arithmetic: Study of numbers and basic operations (addition, subtraction, multiplication, division).
- Algebra: Involves symbols and letters to represent numbers and express mathematical relationships.
- Geometry: Focuses on shapes, sizes, and properties of space.
- Trigonometry: Studies relationships between angles and sides in triangles.
- Calculus: Involves limits, derivatives, integrals, and infinite series.
- Statistics: Collection, analysis, interpretation, presentation, and organization of data.
- Probability: Measures the likelihood of an event occurring.
2. Fundamental Theorems
- Pythagorean Theorem: In a right triangle, ( a^2 + b^2 = c^2 ), where ( c ) is the hypotenuse.
- Fundamental Theorem of Algebra: Every non-constant polynomial has at least one complex root.
- Fundamental Theorem of Calculus: Relates differentiation and integration; provides a way to compute definite integrals.
3. Key Definitions
- Integer: Whole numbers that can be positive, negative, or zero.
- Rational Number: A number that can be expressed as a fraction ( \frac{a}{b} ), where ( a ) and ( b ) are integers and ( b \neq 0 ).
- Irrational Number: A number that cannot be expressed as a simple fraction (e.g., ( \sqrt{2}, \pi )).
- Real Number: All rational and irrational numbers.
4. Mathematical Operations
- Addition (+): Combining numbers to find their total.
- Subtraction (−): Finding the difference between numbers.
- Multiplication (×): Repeated addition of a number.
- Division (÷): Splitting into equal parts or groups.
5. Problem-Solving Strategies
- Understand the Problem: Read carefully and identify what is being asked.
- Devise a Plan: Choose a strategy or formula that applies.
- Carry Out the Plan: Execute your strategy step-by-step.
- Review/Reflect: Check the solution for accuracy and reasonableness.
6. Mathematical Notation
- Variables: Symbols (often letters) representing numbers (e.g., ( x, y )).
- Functions: A relation where each input has a single output (e.g., ( f(x) = x^2 )).
- Equations: A statement that two expressions are equal (e.g., ( 2x + 3 = 7 )).
7. Common Formulas
- Area of a Circle: ( A = \pi r^2 )
- Circumference of a Circle: ( C = 2\pi r )
- Area of a Triangle: ( A = \frac{1}{2} \times base \times height )
- Volume of a Cylinder: ( V = \pi r^2 h )
8. Applications of Mathematics
- Finance: Interest calculations, budgeting, and investments.
- Engineering: Design and analysis using geometric and algebraic principles.
- Statistics: Data analysis for decision-making in various fields.
