Calculus Foundations: Continuity and Differentiability

Understanding how functions behave and change is the cornerstone of calculus. This written course guides you through the essential principles of limits, continuity, and differentiability, turning abstract mathematical theories into clear, actionable knowledge. By working through this comprehensive text-based guide, you will transition from basic algebraic understanding to confidently analyzing functions, determining continuity, and calculating derivatives. You will develop the analytical skills required to solve calculus problems systematically and apply these concepts to real-world scenarios like optimization. What you'll learn: - Understand the foundational concept of limits and how they define continuity - Analyze functions to determine continuity at a point and over an interval - Master the definition of differentiability and its relationship with continuity - Apply fundamental rules of differentiation to find derivatives of various functions - Practice solving step-by-step calculus problems through clear written explanations - Explore modern applications of derivatives in optimization and rate-of-change analysis We begin by establishing a solid baseline of key mathematical terminology and limit theories. From there, you will progress sequentially through continuity analysis, differentiability rules, and practical problem-solving exercises. This course is designed for beginners, high school students, and college learners looking for a clear, step-by-step introduction to calculus, with no prior calculus experience required.
