Integral Calculus is a fundamental branch of mathematics that deals with the concept of an integral, used to calculate areas and volumes, and to solve problems involving complex phenomena such as changing velocities and rates. Coursera's integral calculus catalogue teaches you the tools and techniques required to solve complex mathematical problems using integration. You'll learn the fundamental theorem of calculus, methods of integration, applications of the integral, and how to approach differential equations. This knowledge is crucial for fields such as engineering, physics, economics, and computer science, and will enhance your problem-solving skills in these and other areas.
