Study Notes
Basic Mathematical Concepts
- Mathematics is the study of quantity, structure, space, and change.
- It uses symbols and logic to describe and analyze these aspects.
- Key branches include arithmetic, algebra, geometry, calculus, and statistics.
- Arithmetic involves basic operations like addition, subtraction, multiplication, and division.
- Algebra uses variables to represent unknown quantities and solve equations.
- Geometry deals with shapes, sizes, and positions in space.
- Calculus studies change and motion, using concepts like derivatives and integrals.
- Statistics gathers, analyzes, and interprets data.
Number Systems
- Natural numbers (counting numbers): 1, 2, 3,...
- Whole numbers: 0, 1, 2, 3,...
- Integers: ..., -3, -2, -1, 0, 1, 2, 3,...
- Rational numbers: numbers expressible as a fraction p/q, where p and q are integers, and q ≠ 0.
- Irrational numbers: numbers not expressible as a fraction of two integers. Examples include π and √2.
- Real numbers: the set of all rational and irrational numbers.
- Complex numbers: numbers in the form a + bi, where a and b are real numbers, and i is the imaginary unit (i² = -1).
Arithmetic Operations
- Addition: combining quantities.
- Subtraction: finding the difference between quantities.
- Multiplication: repeated addition.
- Division: separating a quantity into equal parts.
- Order of Operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication and Division (left to right), Addition and Subtraction (left to right).
Algebra
- Variables: symbols representing unknown quantities.
- Equations: statements showing the equality of two expressions.
- Solving equations: finding the variable value making the equation true.
- Inequalities: statements comparing expressions using symbols like <, >, ≤, ≥.
- Linear equations: equations with variables raised to the power of 1.
- Quadratic equations: equations with variables raised to the power of 2.
- Polynomials: expressions comprising variables and coefficients.
Geometry
- Points, lines, and planes: fundamental geometric objects.
- Angles: formed by two rays sharing a common endpoint.
- Polygons: closed figures formed by line segments. Examples include triangles, quadrilaterals, pentagons.
- Circles: closed curves with all points equidistant from a central point.
- Area and perimeter: important geometric measurements.
- Volume: space occupied by a three-dimensional object.
Calculus
- Limits: describe function behavior as input approaches a value.
- Derivatives: measure instantaneous rate of change.
- Integrals: find area under a curve or accumulation.
- Applications: finding maximum/minimum values, calculating areas and volumes.
Statistics
- Data collection: gathering information.
- Data organization: arranging information.
- Data analysis: interpreting and summarizing information.
- Measures of central tendency (mean, median, mode).
- Measures of dispersion (range, variance, standard deviation).
- Probability: likelihood of an event.
- Statistical distributions (normal, binomial, etc.).
- Hypothesis testing: using data to assess statements.
