Problem D please 

1. Suppose we would like to approximate V10 using the Taylor polynomial of order
n = 3 for the function f(x) = Yx centered at a.
a) Identify a good choice for the center a.
Hint: Look for a perfect cube close to 10.
b) Find p3(x) and use it to approximate V10.
c) Find the absolute error of the approximation by assuming the exact value of V10
is given by a calculator.
d) Does the p3(x) you found provide a better approximation of V10 or of V11?
Explain your answer.

Expert Solution
Step 1

From part b:f(x)p3(x)=2+112(x-8)-1288(x-8)2+520736(x-8)3 Using this polynomial we get the approximation of 103  and 113 are:p3(10)=2+112(10-8)-1288(10-8)2+520736(10-8)3=55852592p3(11)=2+112(11-8)-1288(11-8)2+520736(11-8)3=1709768
