IVP Solving: Fourth-Order Taylor Series vs Euler's Method

Описание: Learn how to solve initial value problems (IVPs) for ordinary differential equations (ODEs) using the higher-order Taylor series method. In this tutorial, we focus on the 4th-order Taylor series method, showing how it outperforms Euler’s method by using more derivative terms for better accuracy with the same step size.

What you’ll see:
A practical derivation of the 4th-order Taylor formula
A clear worked example with y’ = y, y(0) = 1
Higher derivatives obtained directly from the ODE
Side-by-side comparison with Euler’s method for the same IVP and step size
Practical tips for computing higher derivatives using algebra or symbolic tools

Key takeaways:
Taylor 4th order uses derivatives up to y^(4), improving local truncation error to O(h^4)
For smooth problems, Taylor methods often deliver smaller error than Euler at the same h
Works for explicit IVPs dy/dx = f(x, y) with manageable derivative calculations

Ideal for students studying numerical methods, applied mathematics, or preparing for engineering exams.
