Delaware Precalculus: What Students Learn
Delaware Precalculus covers a wide range of advanced math topics that bridge high school Algebra and Geometry with Calculus. Aligned to Delaware Math Content Standards, the course gives students the tools they need to succeed in higher-level math and on standardized assessments like the SAT and ACT.
Complex Numbers and the Complex Plane
Students represent complex numbers in both rectangular and polar form on the complex plane. They perform addition, subtraction, multiplication, and conjugation geometrically, and calculate distances and midpoints in the complex plane using modulus and averages.
Trigonometric Functions and the Unit Circle
A large portion of Precalculus focuses on trigonometry. Students learn radian measure, explore the unit circle, and use special triangles to find exact values for sine, cosine, and tangent at key angles. Topics also include:
- Symmetry and periodicity of trigonometric functions
- Modeling periodic phenomena with amplitude, frequency, and midline
- Inverse trigonometric functions and solving trig equations
- Pythagorean identity and addition/subtraction formulas
- Law of Sines, Law of Cosines, and triangle area formulas
Vectors and Matrices
Students work with vectors as quantities having both magnitude and direction. They add, subtract, and scale vectors, and solve real-world problems involving velocity. Matrix topics include addition, subtraction, scalar multiplication, matrix multiplication, determinants, inverses, and using matrices to solve systems of linear equations.
Polynomial and Rational Expressions
Precalculus extends algebraic reasoning to polynomial identities, the Binomial Theorem, and operations on rational expressions. Students learn to add, subtract, multiply, and divide rational expressions and recognize them as a closed system similar to rational numbers.
Conic Sections
Students derive equations for parabolas, ellipses, and hyperbolas from geometric definitions. They construct tangent lines to circles and interpret conic sections in coordinate geometry contexts.
Statistics and Probability
The course includes a thorough treatment of statistics and probability. Students study sample surveys, experiments, and observational studies; use simulations to model random sampling; and calculate conditional probabilities using addition and multiplication rules. Topics also include random variables, probability distributions, and expected value.
