Functions: Relation between a set of inputs and outputs; usually expressed as f(x).

Points: Location in space, dimensionless.
Lines and Line Segments: Straight paths with no thickness; line segment has endpoints.
Angles: Formed by two rays with a common endpoint; measured in degrees.
Shapes:
- Triangles: 3 sides; types include scalene, isosceles, and equilateral.
- Quadrilaterals: 4 sides; types include squares, rectangles, and parallelograms.

Limits: Determines the value of a function as it approaches a certain point.
Derivatives: Measure of how a function changes as its input changes; slope of the tangent line.
Integrals: Measure of the area under a curve; represents accumulation of quantities.

Events: Outcomes or combinations of outcomes in a probability experiment.
Probability Rules:
- Probability of an event (E) = (Number of favorable outcomes) / (Total outcomes).
- Theorem of total probability, Bayes' theorem.

Calculators: For complex calculations.
Graphing Tools: For visual representation of functions and data.
Mathematical Software: Tools like MATLAB, Mathematica for calculations and simulations.

Lines and line segments are straight paths with no thickness, with line segments having defined endpoints.
Angles are formed by two rays sharing a common endpoint, measured in degrees.
Shapes include various forms:
- Triangles have three sides and are classified as scalene, isosceles, or equilateral based on their side lengths.
