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.

congrats on reading the definition of step size. now let's actually learn it.

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?
