Study Notes
Algebra
Algebra is a branch of mathematics that deals with the study of variables and their relationships.
Types of Algebra:
- Elementary Algebra: Deals with solving linear equations and inequalities, graphing lines and circles, and quadratic equations.
- Intermediate Algebra: Covers systems of equations, functions, and graphing.
- College Algebra: Includes advanced topics such as polynomial and rational functions, conic sections, and series and sequences.
Key Concepts:
- Variables: Letters or symbols that represent unknown values.
- Constants: Numbers that do not change value.
- Algebraic Expressions: Combinations of variables, constants, and mathematical operations.
- Equations: Statements that two algebraic expressions are equal.
- Inequalities: Statements that one algebraic expression is greater than, less than, or equal to another.
Algebraic Operations:
- Addition and Subtraction: Combining like terms.
- Multiplication and Division: Distributive property, FOIL method, and factoring.
- Exponents and Logarithms: Rules of exponents, exponential functions, and logarithmic functions.
Solving Equations and Inequalities:
- Linear Equations: Slope-intercept form, point-slope form, and standard form.
- Quadratic Equations: Factoring, quadratic formula, and completing the square.
- Systems of Equations: Substitution method, elimination method, and graphical method.
Functions:
- Domain and Range: Input and output values of a function.
- Types of Functions: Linear, quadratic, polynomial, rational, and exponential functions.
- Graphing Functions: Understanding the behavior and shape of functions.
Applications of Algebra:
- Science and Engineering: Modeling real-world phenomena, optimization problems, and physics.
- Computer Science: Algorithm design, data analysis, and coding theory.
- Economics and Finance: Modeling economic systems, supply and demand, and investments.
