Study Notes
Basic Arithmetic
- Addition (+): Combining two or more numbers to get a sum.
- Subtraction (−): Removing a number from another to find the difference.
- Multiplication (×): Repeated addition of a number.
- Division (÷): Splitting a number into equal parts.
Algebra
- Variables: Symbols (like x, y) representing numbers.
- Expressions: Combinations of numbers and variables (e.g., 2x + 5).
- Equations: Statements that two expressions are equal (e.g., 2x + 5 = 10).
- Solving equations: Finding the value of the variable that makes the equation true.
Geometry
- Shapes: Basic figures (e.g., squares, circles, triangles).
- Perimeter: Total length around a shape.
- Area: Space contained within a shape.
- Volume: Measurement of space in 3D objects.
Trigonometry
- Sine (sin), Cosine (cos), Tangent (tan): Ratios in right triangles.
- Pythagorean theorem: a² + b² = c² (relationship between sides in a right triangle).
Calculus
- Limits: Value that a function approaches as the input approaches a point.
- Derivatives: Measure of how a function changes as its input changes.
- Integrals: Represent accumulation of quantities.
Statistics
- Mean: Average of a set of numbers.
- Median: Middle value in a sorted list.
- Mode: Most frequently occurring number in a set.
- Standard deviation: Measure of data spread around the mean.
Probability
- Probability: Measure of likelihood of an event (0 to 1 scale).
- Independent events: One event does not affect another.
- Dependent events: One event affects the probability of another.
Functions
- Definition: A relation where each input has exactly one output.
- Types of functions: Linear, quadratic, exponential, logarithmic.
- Graphs: Visual representation of functions showing relations between variables.
Number Theory
- Prime numbers: Natural numbers greater than 1 that have no divisors other than 1 and themselves.
- Composite numbers: Natural numbers greater than 1 that are not prime.
- Factors: Numbers that divide another number without leaving a remainder.
Mathematical Logic
- Statements: Declarative sentences that are either true or false.
- Logical operators: AND, OR, NOT (used in constructing logical statements).
- Proofs: Logical arguments that establish the truth of a statement.
Basic Arithmetic
- Addition (+) combines two or more numbers to find their sum.
- Subtraction (−) removes a number from another to find their difference.
- Multiplication (×) is like repeated addition of a number.
- Division (÷) splits a number into equal parts.
Algebra
- Variables act as placeholders for unknown numbers.
- Expressions combine numbers and variables using operations.
- Equations state that two expressions are equal.
- Solving equations involves finding the value of the variable that makes the equation true.
Geometry
- Shapes are basic figures like squares, circles, and triangles.
- Perimeter measures the total length around a shape.
- Area measures the space contained within a shape.
- Volume measures the space occupied by a 3D object.
Trigonometry
- Sine (sin), Cosine (cos), and Tangent (tan) are ratios of sides in right triangles.
- Pythagorean theorem relates the sides of a right triangle: a² + b² = c² (where c is the hypotenuse).
Calculus
- Limits describe the value a function approaches as its input gets close to a specific point.
- Derivatives measure how a function changes as its input changes.
- Integrals represent the accumulation of quantities.
Statistics
- Mean represents the average value of a set of numbers.
- Median is the middle value when a set of numbers is ordered.
- Mode identifies the most frequent number in a dataset.
- Standard deviation measures how data points spread around the mean.
Probability
- Probability measures the likelihood of an event happening, ranging from 0 (impossible) to 1 (certain).
- Independent events don't influence each other's probabilities.
- Dependent events have probabilities that influence each other.
Functions
- A function assigns a unique output to each input.
- Types include linear, quadratic, exponential, and logarithmic functions.
- Graphs visually represent functions and their relationships between variables.
Number Theory
- Prime numbers have only two divisors: 1 and themselves.
- Composite numbers are natural numbers greater than 1 that aren't prime.
- Factors are numbers that divide another number evenly without leaving a remainder.
Mathematical Logic
- Statements are sentences that can be either true or false.
- Logical operators (e.g., AND, OR, NOT) combine statements to create complex expressions.
- Proofs establish the truth of a statement through logical arguments.
