Study Notes
Algebra
-
Definition: A branch of mathematics dealing with symbols and the rules for manipulating those symbols to solve equations.
-
Key Concepts:
- Variables: Symbols used to represent unknown values (e.g., x, y).
- Expressions: Combinations of variables and constants using operations (e.g., 2x + 3).
- Equations: Statements that two expressions are equal (e.g., 2x + 3 = 7).
- Functions: Relations between sets that assign exactly one output for each input (e.g., f(x) = x^2).
-
Common Operations:
- Addition/Subtraction: Combining like terms.
- Multiplication/Division: Distributing and factoring expressions.
-
Types of Equations:
- Linear Equations: Equations of the first degree (e.g., y = mx + b).
- Quadratic Equations: Equations of the second degree (e.g., ax^2 + bx + c = 0).
- Polynomial Equations: Involving variables raised to whole number powers.
-
Inequalities: Expressions showing the relationship between quantities that are not necessarily equal (e.g., x + 5 > 10).
Geometry
-
Definition: A branch of mathematics concerned with the properties and relationships of points, lines, surfaces, and solids.
-
Key Concepts:
- Points, Lines, and Planes: Basic building blocks of geometry.
-
Angles: Formed by two rays with a common endpoint; measured in degrees.
- Types: Acute (< 90°), Right (90°), Obtuse (> 90°).
-
Shapes and Properties:
-
Triangles: Three-sided figures classified by angles (acute, right, obtuse) and sides (scalene, isosceles, equilateral).
- Sum of angles = 180°.
- Quadrilaterals: Four-sided figures (e.g., squares, rectangles, trapezoids).
- Circles: Defined by a center point and radius; properties include circumference (C = 2πr) and area (A = πr^2).
-
Triangles: Three-sided figures classified by angles (acute, right, obtuse) and sides (scalene, isosceles, equilateral).
-
Theorems:
- Pythagorean Theorem: In a right triangle, a^2 + b^2 = c^2 (where c is the hypotenuse).
- Similar Triangles: Triangles with the same shape but different sizes; corresponding angles are equal.
-
Measurement:
- Perimeter: The distance around a shape.
- Area: The space within a shape.
- Volume: The space within a 3D object (e.g., for a cube, V = side^3).
-
Coordinate Geometry: The study of geometric figures using a coordinate system; allows for algebraic methods to solve geometric problems.
