Taylor polynomial:I'm not sure what to do for this. Here's the problem:
"(a) Find the equation of the best quadratic approximation to at x=1. The best quadratic approximation has the same first and second derivatives as at x=1.
(b) Use a computer or calculator to graph the approximation and on the same set of axes. What do you notice?
(c) Use your quadratic approximation to calculate approximate values for ln(1.1) and ln(2)"
Parts b and c, I don't doubt that they'd be easy after getting part a.
So could someone help me with part a?
