This is a Excellent Application on Learning Calculus Includes Video Training and Practice Exam.
Calculus is the mathematical study of change in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations. It has two major branches, differential calculus concerning rates of change and slopes of curves, and integral calculus concerning accumulation of quantities and the areas under curves these two branches are related to each other by the fundamental theorem of calculus.
