Pre-Calculus is a mathematical course that provides the foundation for calculus. It covers topics such as algebra, trigonometry, exponential and logarithmic functions, complex numbers, and statistics. The course is primarily focused on developing students' problem-solving skills and mathematical reasoning abilities. Pre-Calculus is usually taken before calculus and helps students build the necessary background knowledge and skills to succeed in calculus classes. It is a challenging course that requires a solid understanding of algebra and geometry.
