Study Notes
Fundamental Concepts in Math
Basic Arithmetic
- Addition (+): Combining numbers to get a sum.
- Subtraction (−): Taking one number away from another.
- Multiplication (×): Repeated addition of a number.
- Division (÷): Splitting a number into equal parts.
Algebra
- Variables: Symbols (like x, y) representing unknown values.
- Expressions: Combinations of variables, numbers, and operations (e.g., 3x + 2).
- Equations: Mathematical statements asserting two expressions are equal (e.g., 2x + 3 = 7).
- Functions: Relations where each input has one output (e.g., f(x) = 2x + 3).
Geometry
- Points: Exact locations in space, represented by coordinates.
- Lines: Straight paths extending infinitely in both directions.
- Angles: Formed by two rays with a common endpoint, measured in degrees.
-
Shapes:
- 2D: Circles, triangles, squares.
- 3D: Cubes, spheres, cylinders.
Trigonometry
- Sine, Cosine, Tangent: Ratios of sides in right triangles.
- Pythagorean Theorem: a² + b² = c² (relationship between sides of a right triangle).
Calculus
- Limits: The value a function approaches as input approaches a point.
- Derivatives: Measure of how a function changes as its input changes.
- Integrals: Represents accumulation of quantities, area under curves.
Statistics
- Mean: Average of a set of numbers.
- Median: Middle value in a sorted list of numbers.
- Mode: Most frequently occurring value in a data set.
- Standard Deviation: Measure of data dispersion from the mean.
Probability
- Event: Outcome or combination of outcomes from a random experiment.
- Probability Formula: P(Event) = Number of favorable outcomes / Total number of outcomes.
- Independent Events: The occurrence of one event does not affect another.
Number Theory
- Prime Numbers: Natural numbers greater than 1 that have no divisors other than 1 and themselves.
- Factors: Numbers that divide another number without leaving a remainder.
- Multiples: The result of multiplying a number by an integer.
Mathematical Notation
- Sets: Collections of distinct objects (e.g., {1, 2, 3}).
- Inequalities: Expressions that show the relationship of greater than (>) or less than (<).
- Exponents: Indicate repeated multiplication (e.g., x² = x × x).
Problem-Solving Techniques
- Breaking down problems: Simplifying complex problems into smaller, manageable steps.
- Working backwards: Starting from the desired outcome and reversing the operations.
- Checking work: Reviewing calculations for accuracy and consistency.
Fundamental Concepts in Math
Basic Arithmetic
- Addition combines two or more numbers to produce a sum, indicated by the plus sign (+).
- Subtraction involves removing one number from another, represented by the minus sign (−).
- Multiplication represents repeated addition and is denoted by the multiplication sign (×).
- Division divides a number into equal parts, shown with the division sign (÷).
Algebra
- Variables such as x and y serve as symbols for unknown quantities in mathematical expressions.
- Expressions consist of variables, constants, and operators, like 3x + 2, forming an algebraic combination.
- Equations establish a balance between two expressions, exemplified by 2x + 3 = 7.
- Functions define relationships where each input corresponds to exactly one output, represented as f(x) = 2x + 3.
Geometry
- Points signify precise locations in a space, identified through coordinates on a graph.
- Lines are straight entities extending endlessly in both directions, defined mathematically.
- Angles arise from the intersection of two rays at a common point, measured in degrees.
- Shapes are categorized into:
- 2D: Includes objects like circles, triangles, and squares lying on a plane.
- 3D: Comprises solid figures such as cubes, spheres, and cylinders.
Trigonometry
- Sine, Cosine, and Tangent are primary functions that relate angles to side ratios in right triangles.
- The Pythagorean Theorem, a² + b² = c², illustrates the relationship between the sides of a right triangle.
Calculus
- Limits identify the value that a function approaches as the input approaches a specified point.
- Derivatives indicate how a function's value changes with respect to changes in its input.
- Integrals represent the accumulation of quantities, often calculated as the area under curves.
Statistics
- The mean signifies the average, calculated by summing all numbers and dividing by their count.
- The median refers to the middle value in a dataset when arranged in order.
- The mode is the value that appears most frequently in a given dataset.
- Standard deviation measures how much data varies from the mean, indicating dispersion.
Probability
- An event represents any outcome or collection of outcomes from a statistical experiment.
- The probability formula calculates the likelihood of an event as P(Event) = Favorable outcomes / Total outcomes.
- Independent events have outcomes that do not influence one another, maintaining separateness in probabilities.
Number Theory
- Prime numbers are those greater than one with no divisors other than one and themselves.
- Factors are integers that evenly divide another number, leaving no remainder.
- Multiples are achieved by multiplying a number by integers, generating a sequence of products.
Mathematical Notation
- Sets are defined collections of distinct items, denoted with curly braces (e.g., {1, 2, 3}).
- Inequalities express the relationships of numbers using symbols like greater than (>) or less than (<).
