Simpson's Rule and Error Analysis

The video tutorial explains how to use Simpson's Rule to approximate a definite integral and determine the necessary number of subintervals (n) to ensure accuracy within a specified error margin. It covers setting up the problem using the error bounds formula, finding the maximum function value of the fourth derivative, and solving the inequality to find the appropriate n value, emphasizing that n must be even.

What is a key requirement for the number of intervals (n) when using Simpson's Rule?

• n must be even

• n must be a prime number

• n must be odd

• n must be a multiple of 3

What does the error bounds formula for Simpson's Rule help determine?

• The exact value of the integral

• The maximum error in the approximation

• The minimum number of intervals needed

• The average value of the function

In the context of Simpson's Rule, what is the significance of the fourth derivative of the function?

• It determines the function's concavity

• It is irrelevant to the error calculation

• It helps in finding the function's roots

• It is used to find the maximum error

What is the significance of the interval from -2 to 1 in this problem?

• It is the domain of the function

• It is the range for finding the maximum function value

• It is the interval for calculating the integral

• It is where the function is undefined

What is the value of the fourth derivative in the given problem?

• 4

• -4

• 24

• -24

After substituting the maximum function value into the error bounds formula, what is the next step?

• Multiply both sides by 180

• Solve for the integral

• Find the fourth root of both sides

• Divide by the number of intervals

What is the absolute value of the maximum function value of the fourth derivative used in the error bounds formula?

• 12

• 48

• 24

• 4

What is the minimum even number of intervals (n) required to ensure the approximation is within the desired accuracy?

• 5

• 6

• 8

• 4

Why can't the number of intervals (n) be 5 in this problem?

• Because 5 is too large

• Because 5 is too small

• Because 5 is not even

• Because 5 is not a prime number

What is the main goal of using Simpson's Rule in this context?

• To calculate the derivative of the function

• To determine the function's maximum value

• To approximate the integral within a specific error margin

• To find the exact value of the integral
