For the following quesitons, practice answer the following three parts of the questions: (a) Find (b) Find the slope of the tangent line at x=1 if possible, and (c) Find the tangent line equation at x=1.
I shall solve the last problem here and give you some preview of what we will do in chapter 3.
We find and which means that the tangent line is a horizontal line which passes through (1, f(1)) or thus the tangent line eqution is But let's use this example to discuss further.
