- Polynomials: Learning to perform operations with polynomials and factoring them.
- Functions: Exploring different types of functions, including linear, quadratic, and exponential functions.
2. Geometry
Geometry focuses on the properties and relations of points, lines, surfaces, and solids. It helps students develop spatial reasoning and visualization skills. Important topics include:
- Angles and triangles: Understanding the properties of different types of triangles and the relationships between angles.
- Circles: Learning about the properties of circles, including circumference and area.
- Transformational geometry: Studying transformations such as translations, rotations, reflections, and dilations.
3. Trigonometry
Trigonometry is the study of the relationships between the angles and sides of triangles, particularly right triangles. This area of math is essential for various fields, including physics, engineering, and architecture. Key concepts include:
- Sine, cosine, and tangent functions: Understanding these fundamental trigonometric ratios.
- Unit circle: Learning how to use the unit circle to find the values of trigonometric functions.
- Applications: Exploring real-world problems involving angles, distances, and heights.
4. Pre-Calculus
Pre-calculus serves as a bridge between algebra, geometry, and calculus. It consolidates students’ understanding of functions and prepares them for the challenges of calculus. Important topics include:
- Complex numbers: Learning how to perform operations with complex numbers.
- Sequences and series: Understanding arithmetic and geometric sequences.
- Limits: An introduction to the concept of limits, which is fundamental in calculus.
5. Calculus
Calculus is often a high school student's first exposure to advanced mathematics. It deals with the concepts of change and motion. Core topics include:
- Differentiation: Learning how to find the derivative of a function and its applications.
- Integration: Understanding the process of integrating functions and calculating areas under curves.
- Applications of calculus: Exploring real-world applications in physics, economics, and biology.
