Key Concepts in Mathematics

Arithmetic: Basic operations (addition, subtraction, multiplication, division).
Algebra: Use of symbols and letters to represent numbers in equations.
Geometry: Study of shapes, sizes, and properties of space.
Trigonometry: Relationships between angles and sides in triangles.
Calculus: Study of change, involves differentiation and integration.
Statistics: Collection, analysis, interpretation, and presentation of data.
Probability: Study of randomness and uncertainty; likelihood of events.

Pythagorean Theorem: In a right triangle, ( a^2 + b^2 = c^2 ) (where c is the hypotenuse).
Fundamental Theorem of Algebra: Every non-constant polynomial equation has at least one complex root.
Fundamental Theorem of Calculus: Links differentiation and integration; states that differentiation and integration are inverse processes.

Order of Operations: Remember PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
Factoring: Breaking down expressions into multiplied components (e.g., ( x^2 - 9 = (x-3)(x+3) )).
Solving Equations: Techniques include isolating variables, using inverse operations, and applying the quadratic formula.

Coordinate System: Cartesian plane defined by x (horizontal) and y (vertical) axes.
Linear Equations: Represented as ( y = mx + b ); where m is the slope and b is the y-intercept.
Functions: Relation between input (x) and output (y); notation ( f(x) ).

Real-world Problems: Used in fields like physics, engineering, economics, and social sciences.
Data Analysis: Essential for interpreting statistical data, trends, and patterns.
Cryptography: Mathematics is foundational for secure communication and data protection.

π (Pi): Approx. 3.14; ratio of the circumference of a circle to its diameter.
e: Approx. 2.718; base of natural logarithms, important in calculus.

Arithmetic: Involves fundamental operations such as addition, subtraction, multiplication, and division.
Algebra: Manipulates symbols and letters to formulate and solve equations.
Geometry: Explores the properties, dimensions, and relationships of shapes and space.
Trigonometry: Analyzes the connections between the angles and sides of triangles.
Calculus: Investigates rates of change through differentiation and the accumulation of quantities via integration.
Statistics: Concerned with the systematic collection, analysis, interpretation, and presentation of numerical data.
Probability: Studies the likelihood and uncertainty of events occurring in random situations.

Pythagorean Theorem: Expresses that in a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides (( a^2 + b^2 = c^2 )).
Fundamental Theorem of Algebra: Guarantees that every non-constant polynomial equation has at least one complex root.
Fundamental Theorem of Calculus: Establishes the relationship between differentiation and integration, indicating they are inverse processes.
