First-Order Numerical Procedure

Definition

A first-order numerical procedure is an algorithm used to approximate solutions to first-order ordinary differential equations. It involves dividing the interval into small steps and using iterative calculations to estimate values at each step.

Analogy

Imagine trying to climb up stairs in complete darkness. A first-order numerical procedure is like feeling your way up step by step, using your previous position and some information about each step's height to estimate where you are now.

Euler's Method: Euler's method is a specific first-order numerical procedure that uses linear approximations to estimate solutions.

Runge-Kutta Methods: Runge-Kutta methods are more accurate and sophisticated first-order numerical procedures that use weighted averages of multiple estimates at each step.

Taylor Series Method: The Taylor series method expands the function into an infinite sum of terms, allowing for higher accuracy in approximating solutions.
