Question 1.
Define what an initial value problem (IVP) is.
Show hintHide hint
Think about the word 'initial'. What do you think it refers to?
Question 2.
Why is the step size ( $h$ ) important in numerical methods?
Show hintHide hint
Consider how closely we need to check values.
3Question 3.
What is the basis of the Adams–Bashforth method?
- Single-step integration
- Using previous values for prediction
- Only backward values
- Using matrix operations
Show hintHide hint
Remember, this method builds upon prior calculations.
4Question 4.
The choice of step size affects the outcomes of a numerical method. True or False?
- True
- False
Show hintHide hint
Think about how detail-oriented we need to be in calculations.
Question 5.
Using the following ODE $\frac{dy}{dx} = 3y + 2x$ and the condition $y(0) = 1$ , apply the 4-step Adams-Bashforth method to calculate $y(0.4)$ assuming a suitable step size. Clearly outline your steps.
Show hintHide hint
Start with small steps and verify each result sequentially.
Question 6.
Critique the efficiency of the Adams-Bashforth compared to other methods like Euler and Runge-Kutta for long-term integrations. Provide examples.
Show hintHide hint
Analyze the computational demands and error attributes of each method.
