Euler's Method and Error Analysis

The video tutorial explains how to approximate the value of a function using Euler's method. It begins with setting up the problem and explaining the method's application when solving differential equations analytically is difficult. The tutorial provides a step-by-step calculation of the approximation for y(1) using a step size of 0.25. It concludes with a comparison of the approximation to the actual value, calculating the absolute and relative errors, and discussing the acceptability of the approximation.
