Transcribed Image Text:a) Find the MacLaurin series for f (x) =
1
from a known power series and find the interval of
1- 3x
convergence.
b) Find a bound on the remainder when using the 3rd order Taylor polynomial to estimate f (-).
Expert Solution

Step 1
The given function is
(a)
The Maclaurin series of the function is as follows:
which is defined for , with error bound . Therefore using Maclaurin series of the above function, the Maclaurin series of given function can be calculated as:
Which is valid if .
Hence interval of convergence is .
