This series provides an overview of the Fundamental Theorem of Calculus, delving into its significance in calculus and its two essential parts. In each post, we will explore the relationship between differentiation and integration, as well as the application of the theorem in evaluating definite and indefinite integrals. By the end of the series, students will have a solid understanding of how to apply the Fundamental Theorem to solve a variety of calculus problems involving antiderivatives, definite integrals, and area under curves.
