Study Notes
Fundamental Concepts
- Mathematics is a formal system of logical reasoning using symbolic language
- It deals with abstract concepts like sets, numbers, shapes, and structures
- It uses deductive reasoning, where general principles lead to specific conclusions
- Key areas in math include arithmetic, algebra, geometry, calculus, and statistics
- Mathematics is involved in many scientific disciplines, engineering, and computer science.
Number Systems
- Natural numbers (counting numbers): 1, 2, 3, 4, ...
- Whole numbers: 0, 1, 2, 3, ...
- Integers: ..., -3, -2, -1, 0, 1, 2, 3, ...
- Rational numbers: numbers that can be expressed as a fraction p/q, where p and q are integers, and q ≠ 0
- Irrational numbers: numbers that cannot be expressed as a fraction of two integers
- Real numbers: the set of all rational and irrational numbers
- Imaginary numbers: numbers involving the square root of -1 (represented by 'i')
- Complex numbers: numbers in the form a + bi, where a and b are real numbers, and i is the imaginary unit
Arithmetic Operations
- Addition (+): combining quantities
- Subtraction (-): finding the difference between quantities
- Multiplication (× or *): repeated addition
- Division (/ or ÷): distributing a quantity into equal parts
- Exponents (^): repeated multiplication
Algebra
- Deals with symbols and variables to represent unknown quantities
- Uses equations and inequalities to solve problems
- Simplifying expressions: combining like terms, using the distributive property
- Solving equations: isolating the variable
- Factoring polynomials: finding the factors of a polynomial
Geometry
- Focuses on shapes, sizes, and relationships between figures
- Plane geometry: study of two-dimensional shapes (e.g., triangles, circles, quadrilaterals)
- Solid geometry: study of three-dimensional shapes (e.g., cubes, spheres, cones)
- Formulas for area, perimeter, volume, and surface area of various shapes
Calculus
- Study of change and motion
- Differentiation: finding the rate of change of a function
- Integration: finding the accumulated quantity associated with a function
Statistics
- Collection, organization, analysis, interpretation, and presentation of data
- Measures of central tendency (mean, median, mode)
- Measures of dispersion (range, variance, standard deviation)
- Probability: deals with the likelihood of events occurring
Set Theory
- Study of sets, which are collections of objects
- Operations on sets: union, intersection, complement
- Set relations: subset, superset, equality
Logic
- Formal system of reasoning about statements and arguments
- Rules of inference, such as modus ponens and modus tollens
- Truth tables for evaluating the truth or falsity of statements
Problem Solving Strategies
- Understanding the problem statement
- Identifying knowns and unknowns
- Visualizing the problem
- Developing a plan to solve the problem
- Executing the plan
- Evaluating the solution
Applications of Math
- Physics: modeling motion, forces, and energy
