Calculus
- Study of change and motion
- Deals with limits, derivatives, and integrals
- Key concepts:
- Limits (one-sided, two-sided, infinite)
- Derivatives (first, second, higher-order)
- Applications of derivatives (max/min, optimization)
- Integrals (definite, indefinite)
- Applications of integrals (area, volume, work)
Trigonometry
- Study of triangles and their relationships
- Deals with angles, triangles, and circular functions
- Key concepts:
- Angles (degrees, radians, trigonometric functions)
- Triangles (right, oblique, similar)
- Trigonometric identities (Pythagorean, sum, difference)
- Inverse trigonometric functions
- Applications of trigonometry (solving triangles, waves)
Statistics
- Study of data collection, analysis, and interpretation
- Deals with data visualization, probability, and inference
- Key concepts:
- Types of data (quantitative, qualitative, categorical)
- Data visualization (charts, graphs, plots)
- Probability (events, experiments, conditional)
- Measures of central tendency (mean, median, mode)
- Inference (hypothesis testing, confidence intervals)
Algebra
- Variables and constants are used to represent unknown values and numbers in algebraic expressions
- Equations and functions are used to model real-world situations and relationships between variables
- Linear equations have a degree of one and can be represented graphically as straight lines
- Quadratic equations have a degree of two and can be represented graphically as parabolas
- Functions can be composed together to form new functions
- Domain and range of a function define the input and output values respectively
Geometry
- A point is a location in space represented by a set of coordinates
- Lines can be represented by two points or by a slope and y-intercept
- Angles can be classified as acute, obtuse, right, or straight
- Triangles can be congruent or similar based on their side lengths and angles
- Quadrilaterals are four-sided shapes with different properties such as rectangles, squares, rhombi, and trapezoids
- Circles have a center, radius, and circumference, and are used to model real-world objects
Calculus
- Limits are used to define the behavior of a function as the input approaches a certain value
- Derivatives are used to measure the rate of change of a function with respect to the input
- First and second derivatives can be used to find the maximum and minimum values of a function
- Integrals are used to find the area under curves and accumulate quantities
- Applications of integrals include finding the volume of solids and the work done by a force
Trigonometry
- Angles can be measured in degrees or radians
- Trigonometric functions such as sine, cosine, and tangent are used to model periodic phenomena
- Triangles can be classified as right, oblique, or similar based on their angle measurements
- Trigonometric identities such as the Pythagorean identity are used to simplify trigonometric expressions
- Inverse trigonometric functions are used to find the angle measurements given a trigonometric function value
Statistics
- Quantitative data is numerical, qualitative data is categorical, and categorical data is non-numerical
- Data visualization techniques such as charts, graphs, and plots are used to communicate data insights
- Probability is used to model the likelihood of events occurring
- Conditional probability is used to find the probability of an event given another event
- Measures of central tendency such as mean, median, and mode are used to summarize data distributions
- Inference techniques such as hypothesis testing and confidence intervals are used to make conclusions about populations based on sample data
