3 cards from this section. Quick, good the night before a test.
What is Heun's Method primarily used for?
Think about the types of equations we solve with numerical methods.
Name one advantage of using Heun's Method over Euler's Method.
Consider what accuracy means in the context of numerical solutions.
What kind of method is Heun's Method?
Recall the classification of numerical methods based on their order.
True or False: Heun's Method requires only one evaluation per step.
Think about the steps involved in predicting and correcting.
Using Heun’s Method, solve the ODE dy/dx = y with the initial condition y(0) = 1 over the interval [0, 0.5] with a step size of 0.1. What is the estimated value at y(0.5)?
Don't forget to update y at each step using the method.
Discuss the applicability of Heun's Method in stiff ODEs and propose an alternative method. What is the reasoning behind your choice?
Consider the characteristics of stiff equations relating to rapid changes.
