Computations of the Derivative: The Power Rule
Gottfried Leibniz ( ) Sir Isaac Newton ( )

Find the Derivative of:

What’s going on???? Write your own rule! On your sheet of paper come up with a rule that can be used to derive polynomials.

Now try doing a lot with a Little!

AND More Fun-ctions to dErive!

Are you ready for a challenge?
Do it any way!!!!

Rules: Theorem 3.1 Theorem 3.2 Theorem 3.3 For any integer n > 0,
For any constant c, Theorem 3.2 Theorem 3.3 For any integer n > 0,

Enough, STOP THE DRUM ROLL!!!!!
DRUM ROLL PLEASE….. Enough, STOP THE DRUM ROLL!!!!! Theorem 3.4 For any real number r,

Sum and Difference Rules
If f(x) and g(x) are differentiable at x and c is any constant, then:

Examples: Suppose that the height of a skydiver t seconds after jumping from an airplane is given by f(t) = 225 – 20t – 16t2 feet. Find the person’s acceleration at time t. First compute the derivative of this function to find the velocity Second compute the derivative of this function to find the acceleration The speed in the downward direction increases 32 ft/s every second due to gravity.

Given f(x) = x3 – 6x2 + 1 a) Find the equation of the tangent line to the curve at x = 1 y = -9x + 5 b) Find all points where the curve has a horizontal tangent X=0 and x = 4
