These functions help in solving real-life problems involving angles and distances. For example, they can be used to calculate the height of a building or the distance between two objects.
Unit Circle Trigonometry
Unit Circle Trigonometry expands on the concepts learned in right triangle trigonometry. It introduces the unit circle, which is a circle with a radius of 1. By using the unit circle, students can extend the trigonometric functions to any angle, not just those in right triangles.
This allows for a more comprehensive understanding of trigonometry and its applications.
Trigonometric Identities and Equations
Trigonometric Identities and Equations delve into the algebraic manipulation of trigonometric functions. Students learn various identities and equations that help simplify and solve trigonometric expressions and equations.
This includes the Pythagorean identities, sum and difference identities, double-angle identities, and more. Understanding these identities is essential for advanced math courses such as calculus and beyond.

Statistics
Statistics is a branch of mathematics that focuses on the collection, analysis, interpretation, presentation, and organization of data. It plays a crucial role in various fields such as science, business, economics, and social sciences.
In high school, students often encounter statistics as an upper-level math course after completing Algebra 2.
Collecting, Analyzing and Interpreting Data
One of the main objectives of studying statistics is learning how to collect, analyze, and interpret data. Students will acquire skills in designing surveys, conducting experiments, and gathering information from various sources.
They will also learn about different methods and techniques to organize and summarize data in a meaningful way. This includes creating graphs, charts, and tables to present data visually, making it easier to understand and interpret.
Measures of Central Tendency and Spread
Another important aspect of statistics is understanding measures of central tendency and spread. Students will learn how to calculate and interpret measures such as mean, median, and mode, which help determine the average or typical value of a dataset.
They will also explore measures of spread, including range and standard deviation, which provide information about the variability or dispersion of the data. These measures play a vital role in understanding and analyzing data in real-world scenarios.
Probability Distributions
Probability distributions are fundamental concepts in statistics that allow us to understand the likelihood or chance of certain events occurring. Students will delve into probability theory, learning about different types of distributions such as the normal distribution, binomial distribution, and poisson distribution.
They will explore concepts such as probability density functions and cumulative distribution functions, enabling them to make predictions and draw conclusions based on probability.
Studying statistics in high school can provide students with valuable skills that are applicable in various fields and future careers. It equips them with the ability to analyze data critically, make informed decisions, and draw meaningful conclusions.
Understanding statistical concepts can also enhance their problem-solving abilities and improve their overall quantitative literacy. There are numerous online resources and textbooks available to support students in their statistical journey, such as Khan Academy and Statistics How To, which offer tutorials, practice problems, and interactive lessons to reinforce learning.
Calculus
After completing Algebra 2, one of the most common and important math courses to take in high school is Calculus. Calculus is a branch of mathematics that focuses on the concepts of change and motion. It is a challenging but rewarding subject that builds upon the foundation of algebra and trigonometry.
Limits, Derivatives and Integrals
Calculus is divided into two main branches: differential calculus and integral calculus. Differential calculus deals with the concept of limits, derivatives, and rates of change. Students learn how to find the slope of a curve at a specific point, calculate instantaneous rates of change, and solve optimization problems.
Integral calculus, on the other hand, focuses on finding the area under curves and calculating accumulated change.
Did you know? Calculus was developed independently by Sir Isaac Newton and Gottfried Wilhelm Leibniz in the late 17th century. Their work revolutionized mathematics and laid the foundation for modern physics and engineering.
Applications of Calculus
Calculus has countless real-world applications and is used in various fields such as physics, engineering, economics, computer science, and even medicine. For example, in physics, calculus is used to describe the motion of objects, calculate the force of gravity, and analyze the behavior of fluids.
In economics, calculus helps economists model and understand complex systems of supply and demand. In medicine, calculus is used to model the spread of diseases and analyze medical data.
Interesting fact: Calculus was instrumental in predicting the existence of black holes in space. Scientist Karl Schwarzschild used calculus to solve Einstein’s equations and discovered the Schwarzschild radius, which defines the event horizon of a black hole.
AB vs BC Calculus
When it comes to choosing a calculus course, there are typically two options: AP Calculus AB and AP Calculus BC. AP Calculus AB covers a broad range of calculus topics, including limits, derivatives, and integrals.
AP Calculus BC, on the other hand, covers all the topics in AP Calculus AB plus additional topics such as sequences and series, parametric equations, and polar functions.
