Problem 49E
Representing functions by power series Identify the functions represented by the following power series.
Step-by-Step Solution:
Solution 49E
Step 1:
is an infinite geometric series where
and
.
So,
As we know that sum of an infinite geometric series is where
.
Using for the given power series, we get
where
Hence the function represented by the power series is
.
Step 2 of 1
