Study Notes
Key Concepts in Mathematics
1. Branches of Mathematics
- Arithmetic: Study of numbers and basic operations (addition, subtraction, multiplication, division).
- Algebra: Focus on symbols and rules for manipulating those symbols; includes solving equations and inequalities.
- Geometry: Study of shapes, sizes, and properties of space; includes points, lines, angles, surfaces, and solids.
- Trigonometry: Examines relationships between angles and sides of triangles; involves sine, cosine, tangent functions.
- Calculus: Study of change, involves derivatives and integrals; used to analyze functions and motion.
- Statistics: Collection, analysis, interpretation, presentation, and organization of data.
- Probability: Study of likelihood and uncertainty; focuses on random events.
2. Fundamental Theorems
- Pythagorean Theorem: In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides (a² + b² = c²).
- Fundamental Theorem of Algebra: Every non-constant polynomial equation has at least one complex root.
- Fundamental Theorem of Calculus: Connects differentiation and integration; establishes that integration can be used to find the area under a curve.
3. Mathematical Operations
- Addition (+): Combining two quantities to get a total.
- Subtraction (−): Finding the difference between two quantities.
- Multiplication (×): Repeated addition of a number.
- Division (÷): Splitting a number into equal parts.
4. Number Systems
- Natural Numbers: Counting numbers (1, 2, 3, ...).
- Whole Numbers: Natural numbers including zero (0, 1, 2, ...).
- Integers: Whole numbers that can be positive, negative, or zero (..., -2, -1, 0, 1, 2, ...).
- Rational Numbers: Numbers that can be expressed as a fraction (a/b, where b ≠ 0).
- Irrational Numbers: Numbers that cannot be expressed as a simple fraction (e.g., √2, π).
- Real Numbers: All rational and irrational numbers.
5. Functions and Graphs
- Function: A relation that assigns exactly one output for each input.
- Linear Function: A function that creates a straight line when graphed (y = mx + b).
- Quadratic Function: A polynomial function of degree 2 (y = ax² + bx + c).
- Exponential Function: A function where the variable is an exponent (y = ab^x).
6. Problem-Solving Strategies
- Understand the Problem: Read carefully and identify what is being asked.
- Devise a Plan: Determine a strategy or formula to use.
