Basic Differentiation RulesThe CONSTANT Rule:The derivative of a constant function is 0.
Basic Differentiation RulesThe POWER Rule:
In the case of n = 1, the power rule is best thought of as a separate differentiation rule.

Rates of ChangeA function s that gives the position of an object as a function
of time t is called a position function.
Knowing that ,
the Average Velocity is

Rates of Change - Example
Rates of ChangeWhat if we wanted to know the velocity at a specific time
instead of the average velocity over an extended amount of time?
The instantaneous velocity is the derivative of the position function.
Note: Velocity can be negative, zero or positive.The speed is the absolute value of its velocity.
