Students are expressing concerns about their preparation for Calculus 2 (Cal 2) after feeling that their Calculus 1 (Cal 1) course focused primarily on basic concepts. To prepare for Cal 2, it's essential to understand the fundamental theorem of calculus (FTC), differentiation rules, and basic integration techniques. Checking the course syllabus and description for Cal 2 is recommended, as different institutions may cover topics differently. Key areas to focus on include integration techniques, series, and applications of integration. Continuing to study antiderivatives and familiarizing oneself with the FTC will also be beneficial. Overall, a solid grasp of Cal 1 fundamentals will provide a strong foundation for succeeding in Cal 2.
