Study Notes
Algebra
- Definition: Study of mathematical symbols and rules for manipulating these symbols.
-
Key Concepts:
- Variables: Symbols representing numbers (e.g., x, y).
- Expressions: Combinations of variables and constants (e.g., 3x + 2).
- Equations: Statements that two expressions are equal (e.g., 2x + 3 = 7).
- Functions: Relations between a set of inputs and a set of possible outputs (e.g., f(x) = x^2).
- Factoring: Breaking down expressions into products of simpler factors (e.g., x^2 - 4 = (x - 2)(x + 2)).
- Inequalities: Mathematical statements indicating one quantity is less than or greater than another (e.g., x + 4 > 10).
Geometry
- Definition: Study of shapes, sizes, and properties of space and figures.
-
Key Concepts:
- Points, Lines, and Planes: Basic building blocks of geometry.
-
Angles: Formed by two rays; measured in degrees.
- Types: Acute (< 90°), right (90°), obtuse (> 90°).
- Triangles: Three-sided polygons; classified by sides (scalene, isosceles, equilateral) and angles (acute, right, obtuse).
- Quadrilaterals: Four-sided polygons (e.g., squares, rectangles, trapezoids).
- Circles: Defined by a center point and radius; important terms include diameter, circumference, and area.
- Theorems: Key results such as Pythagorean theorem (a² + b² = c² for right triangles).
Calculus
- Definition: Study of change, focusing on limits, derivatives, and integrals.
-
Key Concepts:
- Limits: The value that a function approaches as the input approaches some value.
-
Derivatives: Measure of how a function changes as its input changes; represents slope of the tangent line at a point.
- Notation: f'(x) or dy/dx.
- Rules: Product rule, quotient rule, chain rule.
-
Integrals: Represents accumulation of quantities; area under a curve.
- Definite Integrals: Calculate the area between two points.
- Indefinite Integrals: Find a function whose derivative is the original function (anti-derivative).
- Fundamental Theorem of Calculus: Connects differentiation and integration, showing they are inverse processes.
