Study Notes
Fundamental Concepts
- Mathematics is a formal system of logic and abstract thought used to model and understand the world around us. It covers a range of topics, including arithmetic, algebra, geometry, calculus, and more specialized fields.
- Fundamental areas like arithmetic deal with basic operations on numbers (addition, subtraction, multiplication, division).
- Algebra uses symbols to represent unknown quantities and relationships, leading to general problem-solving methods.
- Geometry studies shapes, sizes, and spatial relationships.
- Calculus examines change and motion, using concepts like derivatives and integrals.
Number Systems
- Counting numbers (natural numbers): Positive whole numbers (1, 2, 3, ...).
- Whole numbers: Includes zero and positive whole numbers.
- Integers: Includes zero, positive, and negative whole numbers.
- Rational numbers: Numbers expressible as a fraction p/q, where p and q are integers, and q is not zero.
- Irrational numbers: Numbers not expressible as fractions.
- Real numbers: The set of all rational and irrational numbers.
- Imaginary numbers: Numbers containing the square root of -1 (represented as 'i').
- Complex numbers: Combine real and imaginary numbers.
Arithmetic Operations
- Addition: Combining two or more numbers.
- Subtraction: Finding the difference between two numbers.
- Multiplication: Repeated addition of a number.
- Division: Finding how many times one number is contained within another.
- Order of Operations (PEMDAS/BODMAS): Rules for the sequence of operations (Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction).
Algebra
- Variables: Letters representing unknown quantities.
- Equations: Statements showing the equality of two expressions.
- Inequalities: Statements showing the relative sizes of two expressions.
- Solving equations: Finding variable values that satisfy the equation.
- Functions: Relationships between input and output values.
- Linear equations: Represent straight lines on a graph.
- Quadratic equations: Represent parabolas on a graph.
Geometry
- Points, lines, planes: Fundamental geometric elements.
- Angles: Formed by two rays sharing a common endpoint.
- Triangles, quadrilaterals, polygons: Shapes with multiple sides and angles.
- Circles: Closed curves equidistant from a central point.
- Area, perimeter, volume: Measurements of shapes.
- Types of triangles (equilateral, isosceles, scalene): Classified by side lengths or angles.
- Congruency, similarity: Concepts related to shape and size.
- Transformations (translations, rotations, reflections, dilations): Changes in shape position and/or size.
Calculus
- Limits: Describe a function's behavior as a variable approaches a specific value.
- Derivatives: Measure the instantaneous rate of change of a function.
- Integrals: Measure the accumulation of a quantity over an interval.
- Applications of Calculus: Used in problems involving motion, optimization, and dynamic systems.
Statistics and Probability
- Statistics: Collection, analysis, and interpretation of data.
- Probability: Measures the likelihood of an event occurring.
- Descriptive statistics: Summarizing and describing data.
- Inferential statistics: Drawing conclusions about a population from a sample.
