Series | Limit Comparison Test: Example 2

The video tutorial explains how to evaluate the convergence of a mathematical series using specific criteria. It begins with a problem statement and introduces the criteria for convergence. The tutorial then derives expressions for a sub N and B sub N, followed by a detailed calculation of the limit. The conclusion is drawn based on the limit's value, determining whether the series converges or diverges.

What is the main problem discussed in the video?

• Finding the roots of a polynomial

• Solving a quadratic equation

• Evaluating the convergence of a series

• Calculating the derivative of a function

What is the role of B sub N in determining the convergence of the original series?

• It helps in calculating the derivative

• It determines the convergence or divergence of the original series

• It is irrelevant to the series

• It is used to find the roots of the series

How is B sub N simplified in the video?

• By taking the highest power in both the numerator and denominator

• By ignoring the highest power of N

• By adding a constant to the series

• By multiplying the series by a constant

What is the significance of the highest power of N in the algebraic manipulation?

• It is used to find the roots of the series

• It is ignored in the calculations

• It is used to simplify the series

• It is irrelevant to the series

What happens to the series if the limit is exactly zero?

• The series diverges

• The series converges

• The series becomes undefined

• The series oscillates

What is the final conclusion about the original series based on B sub N?

• The original series converges

• The original series diverges

• The original series is undefined

• The original series oscillates

Why is the series 4 / N to the one third considered a divergent P series?

• Because P is greater than 1

• Because P is equal to 1

• Because P is less than 1

• Because P is negative
