5.07 - Derivatives using a TI-84+

Pre-Work:

I) Watch, Read, & Note (make sure you write down the keystrokes for each process, and practice this using your calculator!):

1)  Example 1 

Find the derivative of f(x)=x^2+2x at

a) x=4 

(this is the same as finding f'(4))

b) x=15 

(this is the same as finding f'(15))

Watch "Finding the derivative at a point using TI-84 calculator" for how to do it using a calculator.

2) Example 2

Find the derivative of f(x)=x^(-3)-2x^2+4x+60 at x=2

 Watch " Finding the derivative at a point using  TI 84 calculator" for the answer using your calculator.

3) Example 3

Find the derivative of f(x)=0.3x^9-3x+7  at x=2

Watch " Finding the derivative at a point using  TI 84 calculator" for the answer using your calculator.

4) Notes: Finding Numerical Derivatives
