DIFFERENTIAL CALCULUS
differential calculus is study of definition, properties and application of derivative of a function.
it will study how a derivative of a function will behave in a given domain in a particular point. the process of finding a derivative is called differentiation.
A function is denoted as f then differential function is denoted as f ' called as f prime.

CALCULUS
calculus as you all know is a study of change. its one of the branch of mathematics which is interesting and mind blowing. there are 2 branches in this

1. differential calculus
2. integral calculus

lets see about differential calculus
