Question 1

What is meant by consistency in numerical methods?

A) The numerical method always yields exact results.
B) The local truncation error approaches zero as step size approaches zero.
C) The error remains constant regardless of step size.

💡 Hint: Think about how errors behave as calculations become finer.

Question 2

True or False: A consistent numerical method guarantees accurate results for all step sizes.

True
False

💡 Hint: Consider if consistency alone can ensure accuracy.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Suppose you have a numerical method that uses step sizes of h = 0.1 and h = 0.01. Compare the LTE at both sizes for consistency.

💡 Hint: Compare the results of LTE at both h values.

Challenge 2 Hard

Discuss the implications of using a numerical method that exhibits inconsistency in a real-world application like engineering.

💡 Hint: Think about what happens if calculations are inaccurate in critical structures.
