Calculus is the branch of Maths which involves the study of 'Rate of Change' by splitting or joining small parts. It is a one of the major part of studies in engineering. Calculus contains two branches: differential calculus and integral calculus. Differential calculus splits up an area into small parts to calculate the rate of change. Integral calculus joins small parts to calculates the area or volume. In short, it is the method of reasoning or calculation.
