(a)
The interval of convergence of the series
(a)
Answer to Problem 35E
The interval of convergence
Explanation of Solution
Given information:
The given series is
Formula used:
Calculation:
Summation is expressed as
This is an infinite geometric progression.
Sum is given for an infinite geometric progression is given by
Where a is first term and r is common ratio, also
Here,
Thus interval of convergence
Conclusion:
The interval of convergence
(b)
The interval of convergence absolutely of the series
(b)
Answer to Problem 35E
The interval of absolute converges
Explanation of Solution
Given information:
The given series is
Formula used:
Calculation:
Summation is expressed as
This is an infinite geometric progression.
Sum is given for an infinite geometric progression is given by.
Where a is first term and f is common ratio, also
Here,
Thus interval of absolute converges
Conclusion:
The interval of absolute converges
(c)
The interval of convergence conditionally of the series
(c)
Answer to Problem 35E
All point or interval of convergence, series converges absolutely.
Explanation of Solution
Given information:
The given series is
Formula used:
Calculation:
None
From above two part, Observe that the at all point or interval of convergence, series converges absolutely.
Conclusion:
All point or interval of convergence, series converges absolutely.
