Step size

from class:

Calculus II

Definition

Step size is the interval between successive points used in numerical methods for solving differential equations. It determines the accuracy and computational cost of the solution.

5 Must Know Facts For Your Next Test

  1. Step size, often denoted as $h$, is a crucial parameter in Euler's method and other numerical techniques.
  2. A smaller step size generally increases the accuracy of the numerical solution but also requires more computations.
  3. Choosing an appropriate step size involves a trade-off between computational efficiency and accuracy.
  4. In adaptive step-size methods, the step size can change dynamically based on error estimates.
  5. Large step sizes can lead to significant errors or instability in the numerical solution.

Review Questions

  • Why does a smaller step size typically result in a more accurate solution?
  • How does changing the step size affect computational cost?
  • What is an adaptive step-size method?
