Euler's Method is a numerical technique used to approximate the solution of an ordinary differential equation (ODE) with a given initial value. It's a first-order method, meaning it uses the value at the current time step to estimate the value at the next time step. The method works by taking small steps forward in time, using the derivative at the current point to estimate the change in the function's value. Understanding its derivation, practical implementation, and associated error is crucial for effective application.
This worksheet covers the fundamental aspects of Euler's Method, providing exercises to reinforce your understanding of its derivation, implementation, and error analysis.
