Study Notes
Key Concepts in Mathematics
1. Branches of Mathematics
- Arithmetic: Basic operations (addition, subtraction, multiplication, division).
- Algebra: Study of mathematical symbols and rules for manipulating them. Includes solving equations and working with variables.
- Geometry: Study of shapes, sizes, and properties of space. Includes points, lines, angles, surfaces, and solids.
- Trigonometry: Study of relationships between angles and sides of triangles. Key functions: sine, cosine, tangent.
- Calculus: Study of change and motion. Involves differentiation (finding rates of change) and integration (finding areas under curves).
- Statistics: Study of data collection, analysis, interpretation, and presentation. Includes concepts like mean, median, mode, variance, and probability.
- Discrete Mathematics: Study of mathematical structures that are fundamentally discrete rather than continuous. Includes graph theory and combinatorics.
2. Fundamental Theorems
- 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.
- Central Limit Theorem: The distribution of sample means approaches a normal distribution as the sample size increases, regardless of the original distribution.
3. Important Mathematical Symbols
- x, y, z: Variables, often used to represent unknown quantities.
- =: Equals, indicating equality between two expressions.
- +/-: Plus/Minus, indicating a value can be either positive or negative.
- ∑: Summation, representing the sum of a sequence of numbers.
- ∫: Integral, representing the area under a curve.
4. Common Mathematical Operations
- Addition (+): Combining two or more numbers to get a sum.
- Subtraction (−): Taking one number away from another to get a difference.
- Multiplication (×): Repeated addition of a number.
- Division (÷): Splitting a number into equal parts.
5. Mathematical Logic
- Statements: Propositions that are either true or false.
-
Logical Operators:
- AND (∧)
- OR (∨)
- NOT (¬)
-
Quantifiers:
- Universal (∀): For all.
