1. Use the formal definition of the derivative and your TI-89 to find the derivative of f(x) = 2x³ at x = 1.
2. Use the TI-89 derivative key to find the derivative of f(x) = 2x³ at x = 1.
3. Use the TI-89 derivative key to find the derivative of f(x) = 2x³.
4. Graph f(x) = 2x³ in a [-3, 3] x [-10, 10] window then use the tanimate program with a HIGH sampling rate to illustrate the derivative of f(x) = 2x³. Use the program to illustrate the value of the derivative at x = 1.
5. Find the equation of the line tangent to f(x) = 2x³ at x = 1. Graph f(x) = 2x³ together with the tangent line and then zoom in to show local linearity.
