Step-size refers to the size or interval between consecutive values when working with sequences, series, or iterative processes. It determines how finely we divide our domain into smaller parts for analysis.
Delta x (Δx): A notation used to represent the step-size or change in x-values.
Iteration: The process of repeating a sequence of steps or calculations to approach a desired result.
Convergence: When an iterative process approaches a specific value or solution as the step-size decreases.
