Study Notes
Number Systems
- Natural Numbers: 1, 2, 3,... (positive integers)
- Whole Numbers: 0, 1, 2, 3,... (non-negative integers)
- Integers:..., -3, -2, -1, 0, 1, 2, 3,... (positive and negative whole numbers, including zero)
- Rational Numbers: a/b, where a and b are integers, and b ≠ 0 (fractions)
- Irrational Numbers: cannot be expressed as a/b, where a and b are integers (e.g. π, e)
- Real Numbers: includes rational and irrational numbers
- Complex Numbers: a + bi, where a and b are real numbers, and i is the imaginary unit (i² = -1)
Algebra
- Variables: letters or symbols that represent unknown values
- Constants: numbers
- Expressions: combinations of variables, constants, and mathematical operations
- Equations: statements that two expressions are equal
- Inequalities: statements that one expression is greater than, less than, or equal to another
Geometry
- Points: locations in space, represented by coordinates (x, y) in 2D, or (x, y, z) in 3D
- Lines: sets of points extending infinitely in two directions
- Rays: lines extending from a single point
- Angles: formed by two rays sharing a common endpoint
- Triangles: polygons with three sides and three angles
Calculus
- Limits: the behavior of a function as the input approaches a certain value
- Derivatives: rates of change of functions with respect to the input
- Integrals: accumulation of rates of change over a defined interval
- Differentiation: finding the derivative of a function
- Integration: finding the integral of a function
