Study Notes
Basic Arithmetic Operations
- Addition involves combining two or more numbers to find their total.
- Subtraction involves finding the difference between two numbers.
- Multiplication involves repeatedly adding a number to itself a specific number of times.
- Division involves splitting a number into equal parts.
Number Systems
- Natural numbers are positive whole numbers (1, 2, 3...).
- Whole numbers include zero and positive whole numbers (0, 1, 2, 3...).
- Integers include zero, positive whole numbers, and negative whole numbers (...-2, -1, 0, 1, 2...).
- Rational numbers can be expressed as a fraction p/q where p and q are integers, and q is not zero.
- Irrational numbers cannot be expressed as a fraction.
- Real numbers include all rational and irrational numbers.
- Imaginary numbers are numbers that, when squared, result in a negative number.
Algebra
- Variables represent unknown quantities.
- Equations state that two expressions are equal.
- Inequalities show a relationship where one expression is greater than or less than another.
- Linear equations represent a straight line on a graph.
- Quadratic equations involve a variable raised to the second power.
- Exponents represent repeated multiplication.
- Polynomials are expressions involving variables and their exponents.
Geometry
- Points are locations in space.
- Lines are straight paths extending infinitely in two directions.
- Angles are the space between two intersecting lines.
- Triangles have three sides and three angles.
- Polygons are two-dimensional shapes with straight sides.
- Circles are perfectly round shapes.
- Area measures the space inside a two-dimensional shape.
- Perimeter measures the distance around a two-dimensional shape.
- Volume measures the space occupied by a three-dimensional object.
- Solid figures are three-dimensional shapes.
Measurement
- Units of measurement are used to quantify physical quantities.
- Standard units are used for consistency.
- Common units include meters, centimeters, kilometers, grams, kilograms, liters, seconds, minutes, hours.
Data Analysis
- Data collection involves gathering information.
- Data organization involves arranging data in a structured way.
- Data presentation involves displaying data in charts, graphs, or tables.
- Data interpretation involves analyzing data to derive insights.
- Measures of central tendency (e.g., mean, median, mode) summarize data.
- Measures of variability (e.g., range, standard deviation) describe the spread of data.
Statistics
- Statistics is the science of collecting, organizing, analyzing, interpreting, and presenting data.
- Frequency distributions show how often different values occur.
- Probability measures the likelihood of an event happening.
- Samples are representative portions of a population.
- Populations are the entire group being studied.
Functions
- A function assigns exactly one output value to each input value.
- Functions can be represented graphically, with tables, or algebraically with equations.
- Linear functions produce a straight line on a graph and often follow the form y = mx + b.
- Quadratic functions form a parabola on a graph and usually follow the form y = ax² + bx + c.
- Exponential functions involve an exponent and can often show growth or decay.
- Logarithmic functions are the inverse of exponential functions.
Trigonometry
- Trigonometry deals with relationships between angles and sides of triangles.
- Trigonometric functions (sin, cos, tan) relate angles and sides.
- Applications of trigonometry are common in surveying, navigation, and engineering.
Calculus
- Calculus studies change and accumulation.
- Differential calculus deals with rates of change (derivatives).
- Integral calculus deals with accumulation of quantities (integrals).
- Applications include calculating areas, volumes, and velocities.
