Course: Calculus I
Topic: Derivatives
Subtopic: Definition of Derivative

Overview

Calculus I is called Differential Calculus because it's main focus is on differentiating a function resulting in its derivative. This is the process into which we delve today :) In this lesson we introduce derivatives, study the formal definition of derivative, and learn that a derivative is (1) a rate of change, (2) the slope of the tangent line to a curve, and (3) the velocity of a point moving on a curve. Useful stuff in engineering and physical sciences!

Objectives

By the end of this topic you should know and be prepared to be tested on:
