Series | Convergent p-Series: 4 Examples

The video tutorial introduces the p-Series Test, a simple yet crucial tool for determining the convergence or divergence of series. It explains the structure of a p-Series, where the denominator is n raised to a power p, and the outcome depends on whether p is greater than, less than, or equal to 1. Several examples are provided, illustrating both convergent and divergent series, including those with non-traditional numbers like pi and radical notation. The harmonic series is highlighted as a special case of the p-Series, emphasizing its divergence when p equals 1. The tutorial underscores the importance of recognizing p-Series for further tests like the direct comparison test.

What is the primary purpose of the p-Series Test?

• To find the sum of a series

• To identify the type of series

• To determine if a series converges or diverges

• To calculate the limit of a sequence

In a p-Series, what does the variable 'p' represent?

• The constant added to the series

• The numerator of the series

• The starting point of the series

• The power to which n is raised in the denominator

If p is greater than 1 in a p-Series, what can be concluded about the series?

• The series diverges

• The series converges

• The series oscillates

• The series is undefined

What is the result of a p-Series when p is less than 1?

• The series diverges

• The series is constant

• The series is finite

• The series converges

How can the series 1 over the square root of n be expressed as a p-Series?

• 1 over n to the power of 1/2

• 1 over n to the power of 1

• 1 over n to the power of 3

• 1 over n to the power of 2

What is the significance of the Harmonic Series in the context of p-Series?

• It is a convergent series

• It is neither convergent nor divergent

• It is not related to p-Series

• It is a divergent series and a special case of p-Series

Why is it important to recognize p-Series in mathematical analysis?

• They are crucial for determining convergence or divergence in comparison tests

• They help in solving differential equations

• They simplify complex numbers

• They are used to calculate integrals
