Question 1.
What type of polynomial does the Trapezoidal Rule use for numerical integration?
Show hintHide hint
What shape do trapezoids form?
Question 2.
What is the error rate of Simpson's Rule compared to the Trapezoidal Rule?
Show hintHide hint
Think about both methods' error orders.
3Question 3.
What is the primary advantage of using Simpson's Rule over the Trapezoidal Rule?
- Easier implementation
- Higher accuracy
- Lower computational cost
Show hintHide hint
Think about how each rule approximates the curve.
4Question 4.
True or False: The error of the trapezoidal rule becomes negligible as you approach zero for step size.
- True
- False
Show hintHide hint
Recall the error proportionality relationship.
Question 5.
Using f(x) = sin(x), calculate the area under the curve from 0 to π/2 using both Trapezoidal and Simpson's rules with n = 4 intervals. Analyze which method yields less error and why.
Show hintHide hint
Consider the behavior of sin(x) in multiple intervals.
Question 6.
A smooth function's integral is calculated using both methods. Outline the implications of choosing a method depending on the smoothness of the function and computational resources.
Show hintHide hint
Reflect on the characteristics of the functions involved.
