I need help with the following please.

Section 10.9: Problem 8 Previous Problem Problem List Next Problem (1 point) Use Taylor series you already know to find the first five coefficients of the Taylor series generated by f (x) = In(9 + x) at x = 0. Taylor series is > Cn a" with n=0 CO = 91 = 0 = C = CA Section 10.9: Problem 10 Previous Problem Problem List Next Problem (1 point) Use the fourth-order Taylor polynomial for e" at a = 0 to approximate the value of el/2. e1 /2 ~ Use the Taylor series remainder estimate to bound the error in your approximation above, where the error is the absolute value of the difference between the a value and your approximation. Error Section 10.9: Problem 11 Previous Problem Problem List Next Problem (1 point) Let P2 () be the second-order Taylor polynomial for cos a centered at a = 0. Suppose that 2 () is used to approximate cos a for (x|
