Calculus Foundations: Continuity, Differentiability, and Derivatives

Calculus is the mathematical language of change, but mastering it requires a rock-solid grasp of its foundational pillars. This text-based course guides you step-by-step through the core principles of continuity, differentiability, and the derivative. By reading through clear, structured explanations and working through practical mathematical exercises, you will transition from memorizing formulas to truly understanding how functions behave. You will gain the analytical skills needed to solve complex calculus problems with confidence. What you'll learn: - Understand the formal definitions of limits, continuity, and one-sided limits - Analyze functions to determine where they are continuous or discontinuous - Master the concept of differentiability and its relationship to continuity - Apply fundamental rules of differentiation, including the product, quotient, and chain rules - Solve real-world rate of change and optimization problems using derivatives - Practice step-by-step mathematical proofs and algebraic simplifications The course begins with foundational definitions of limits and continuity before moving systematically into differentiability and practical derivative rules. You will progress from basic conceptual reading to solving comprehensive calculus exercises at your own pace. This course is designed for high school students, pre-university learners, and beginners looking for a clear, self-paced introduction to calculus with no prior advanced math experience required.
