Question 1.
Define stability in the context of numerical methods.
Show hintHide hint
Think about how errors affect the results over time.
Question 2.
What does convergence mean?
Show hintHide hint
Consider what happens when you make the step size smaller.
3Question 3.
What does stability in numerical methods ensure?
- Errors grow indefinitely
- Errors are controlled
- No errors occur
Show hintHide hint
Remember the definition of stability.
4Question 4.
True or False: Convergence means the numerical solution moves further away from the exact solution as the step size decreases.
- True
- False
Show hintHide hint
Think about the goal of solving ODEs.
Question 5.
Consider a numerical method where a large truncation error occurs at each step. Explain how this impacts stability and convergence.
Show hintHide hint
Think about how errors compound in numerical methods.
Question 6.
You are tasked with solving a stiff ODE. What steps can you take to ensure your method is both stable and convergent?
Show hintHide hint
Consider the properties of methods suitable for stiff problems.
