About 1. Basics before calculus
This chapter serves as the essential foundation for calculus by reviewing the algebraic and trigonometric concepts you must master before moving forward. It focuses on understanding functions, their domains and ranges, and how to manipulate equations, ensuring that you have the necessary mathematical vocabulary and computational fluency required for advanced study. Without a solid grasp of these pre-calculus basics, the new concepts in calculus would be nearly impossible to understand or apply correctly.
The second major component of this chapter is the introduction to the coordinate plane and the behavior of different types of functions, such as linear, polynomial, exponential, and logarithmic models. Students learn to visualize how these functions behave graphically and numerically, which builds the intuition needed to later understand rates of change and accumulation. By strengthening these fundamental skills now, students can focus entirely on learning new calculus ideas later without getting stuck on basic algebraic errors.
