Study Notes
Unary and Binary Operations
- A unary operation involves a single operand, essential in functions and calculations.
- An operand is the mathematical object that an operator acts upon.
- A binary relation compares two operands, illustrating relationships between values.
Equations and Their Types
- An equation is a mathematical statement indicated by an '=' symbol, showing equality between two expressions.
- An identity is an equation valid for every real number within the variable's domain.
- A conditional equation holds true for specific values but may be false for others.
- A contradiction has no solution in real numbers; no values satisfy the equation.
Solutions and Sets
- A solution is a number that, when substituted into an equation, makes it true.
- The solution set encompasses all possible solutions to an equation, forming a complete collection of valid answers.
Graphing Equations
- The graph of an equation is defined by all points whose coordinates represent solutions to the equation.
- Another phrasing of the graph's definition highlights the importance of satisfying the equation.
Solving Equations
- Solving an equation entails finding all solutions, resulting in the comprehensive solution set.
Equations and Inequalities
- Equivalent equations have identical solution sets, meaning they yield the same results despite differing forms.
- A simplest equation features one variable and one constant, simplifying the solving process.
- A linear equation in one variable takes the form ax + b = 0, with 'a' and 'b' being real numbers where not both can be zero.
Understanding Inequalities
- An inequality includes an inequality symbol, comparing two expressions similar to equations.
- A solution of an inequality makes the inequality true when substituted for its variable(s).
- The solution set of an inequality is the full collection of solutions that satisfy the inequality.
- The graph of an inequality includes all points satisfying the inequality conditions, indicating valid solutions.
Equivalent Inequalities
- Equivalent inequalities possess matching solution sets, allowing for alternative expressions of the same relationship.
- A simplest inequality features one variable on one side and one constant on the other, mirroring the format of simplest equations.
Quadratic Concepts
- The quadratic formula provides solutions for quadratic equations, defined by coefficients a, b, and c.
- A quadratic equation in one variable is structured as ax² + bx + c = 0, with 'a' non-zero, representing a parabolic relation in graphing contexts.
