The derivative of a constant function is 0. For any real number, c :

1. The Constant Rule

BASIC DIFFERENTIATION RULES

The slope of a horizontal line is 0.

The derivative of a constant function is 0.

y

A.) B.) C.) D.)

2.   The Single Variable Rule:

The derivative of x is 1.  

Think graphically about the line y = x.

3.  The Power Rule

If n is a rational number then the function  is differentiable and  

EX #3:  Use the power rule to find the derivatives of the          following, if:

4.  The General Power Rule: 

 real numbers, is, where a and n areThe derivative of the term 

STEPS:

1.  Multiply the coefficient by the variable's exponent.       If no coefficient is stated ­­ in other words, the       coefficient equals 1­­ the exponent becomes the      new coefficient.2.  Subtract 1 from the exponent.

A.) B.)

C.) D.)

EX #4:  Use the general power rule to find the     derivatives of the following, if:

5.  The Sum and Difference Rules: 

The derivative of a sum or difference is the sum or difference of the derivatives.

EX #4:  The derivative of the sine function is the cosine function.    Consider where the sine function increases, the cosine    function is positive and vice versa!

Graphing Derivatives with a Calculator

You will enter the function as a function of x, to be evaluated at the value of x, instead of an actual number value. 

TI‐83+ or TI‐84+

Use the numeric derivative operation 

(MATH > 8) in the graph editor screen. 

TI‐Nspire CX 

Use the template menu in the graph editor screen

EX #5: Using the limit definition for the derivative                           

we can derive           for each of the following trigonometric functions.  You will verify the derivative of the sine and cosine functions by using the sum and difference formulas that we learned in Pre­Calculus.

EX #5:  Find the derivative of the sine function by using                     the limit process.
