3 cards from this section. Quick, good the night before a test.
What is the formula for Euler’s Method?
Think about how we use the current point to find the next one.
Name one advantage of the Improved Euler Method.
Consider how it calculates slopes.
What is a primary use of numerical methods?
Think of situations where exact answers are hard to come by.
True or False: The Runge-Kutta method requires very small step sizes to maintain accuracy.
Consider how Runge-Kutta differs in approach from simpler methods.
Derive the Improved Euler’s Method formula from Euler’s Method by considering the slopes at the start and end of an interval.
Remember that you are taking two different slopes into account.
Using RK4, solve dy/dx = 3y + 2, y(0)=1, over the interval [0, 0.2] and discuss the importance of each step.
Follow the RK4 formula step-by-step for calculations.
