Study Notes
Branches of Mathematics
- Arithmetic: Basic operations (addition, subtraction, multiplication, division).
- Algebra: Study of symbols and rules for manipulating these symbols; includes solving equations.
- Geometry: Study of shapes, sizes, and properties of space; involves points, lines, angles, and surfaces.
- Trigonometry: Deals with relationships between the angles and sides of triangles; includes functions like sine, cosine, and tangent.
- Calculus: Study of change and motion; includes derivatives and integrals.
- Statistics: Collection, analysis, interpretation, presentation, and organization of data.
- Discrete Mathematics: Study of mathematical structures that are fundamentally discrete rather than continuous.
Fundamental Concepts
- Numbers: Different types of numbers (natural, whole, integers, rational, irrational, real, complex).
- Functions: A relation between a set of inputs and outputs; types include linear, quadratic, polynomial, and exponential functions.
- Equations and Inequalities: Expressions that show equality or inequality; methods for solving (graphing, substitution, elimination).
- Graphs: Visual representations of equations and functions; includes Cartesian coordinates, slopes, and intercepts.
Mathematical Operations
- Order of Operations: PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
- Factoring: Breaking down numbers or expressions into their component factors.
- Exponents: Represent repeated multiplication; laws of exponents govern their manipulation.
- Roots: The inverse operation of exponentiation; includes square roots and cube roots.
Key Theorems
- Pythagorean Theorem: In a right triangle, a² + b² = c², where c is the hypotenuse.
- Fundamental Theorem of Algebra: Every non-constant polynomial equation has at least one complex root.
- Mean Value Theorem: Relates the average rate of change of a function to its instantaneous rate of change at some point in the interval.
