(a) Evaluate the integral:
dx
x2 + 4
Your answer should be in the form k, where k is an integer. What is the value of k?
d
1
-arctan(x)
dx
Hint:
x2 + 1
k =
(b) Now, let's evaluate the same integral using a power series. First, find the power series for the function
32
.. Then, integrate it from 0 to 2, and call the result S. S should be an infinite series.
x2 + 4
f(x)
What are the first few terms of S?
an =
aj =
az =
az =
a4 =
(c) The answers to part (a) and (b) are equal (why?). Hence, if you divide your infinite series from (b) by k
(the answer to (a)), you have found an estimate for the value of T in terms of an infinite series.
Approximate the value of T by the first 5 terms.
(d) What is the upper bound for your error of your estimate if you use the first 8 terms? (Use the
alternating series estimation.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2f443b9c-0cad-48bf-9ffd-5fa4ac707b4a%2F38f32514-a6cd-4055-9b0e-9e7432949215%2F1khl4rg_processed.png&w=3840&q=75)
