Ordinary Differential Equations

Ordinary Differential Equations (ODEs) involve equations with one or more functions and their derivatives. First-order ODEs specifically deal with equations involving the first derivative of a function. Solving ODEs analytically can be challenging or impossible for complex equations, so numerical methods are often employed. Common numerical methods for first-order ODEs include:

Euler's Method: A simple, first-order technique that approximates solutions using linear steps.
Runge-Kutta Methods: Higher-order methods like RK4 provide more accurate solutions by considering multiple intermediate points.
Improved Euler's Method: A predictor-corrector method that refines Euler's approach for better accuracy.

These methods are essential for modeling real-world systems in engineering, physics, and biology.

This was a final project for ODE Spring'23 semester at RVCC, Branchburg. The algorithm used is not memory and time efficient. You can use more precise tools in the resources at the end of the page. If you have any issues, contact me by clicking the support.

Runge-Kutta

You can solve ODE numerically using Runge-Kutta by typing into the input box below. Solutions are rounded to three decimal places by default. The equation should be written in the form "y'(x)={f(x,y)}"
