## What is Derivative ? Definition of Derivative in Calculus – Concept of Derivative

This video introduces basic concept required to understand the derivative calculus. We understand geometrically as well as by definition of derivative.Derivative is important part of calculus in Mathematics. Before learning derivative calculus, we should study limits & continuity in Calculus to very well understand the definition of derivative, the geometry of derivative. We should have the concept of limit calculus at a point. Derivative is no more than a slope of secant line of a curve. Derivative can be defined in one line – rate of change of a function.In this video lesson of derivative we define derivative what exactly derivative is in geometric way. After learning this derivative lesson of calculus I hope you will get some concepts in Derivative of Calculus.
