    3 cards from this lesson. Good the night before a test.

Try these first

  1. 1.

    Define multistep methods in the context of solving ODEs.

    Hint

    Focus on how values influence predictions.

  2. 2.

    What does h represent in the Adams-Bashforth formula?

    Hint

    Consider the spacing in your calculations.

  3. 3.

    What does the general formula of the Adams-Bashforth method rely on?

    • Future values
    • Past values
    • Random values
    Hint

    Think about the meaning of 'predictor' in the method.

  4. 4.

    The constants b_j in the Adams-Bashforth formula are derived from:

    • True
    • False
    Hint

    Focus on the weight of past evaluations.

  5. 5.

    Given f(x, y) = sin(x) + y^2, calculate y(0.3) using the 4-step Adams-Bashforth method with h = 0.1, using initial values from a single-step method.

    Hint

    Watch your previous evaluations closely when applying constants!

  6. 6.

    Discuss the stability of the Adams-Bashforth method compared to implicit methods. Under what conditions can the explicit method fail?

    Hint

    Reflect on how to balance accuracy with choice of step size.
