Numerical Methods and Differential Equations

The video tutorial introduces numerical methods for solving first-order differential equations that cannot be solved analytically. It explains the concept of linearization and how it can be used to approximate functions locally. The tutorial then focuses on Euler's method, a numerical technique for approximating solutions to differential equations. The method is explained in detail, followed by a step-by-step example to demonstrate its application. Finally, the video compares the results of Euler's method with analytical solutions, highlighting the accuracy and limitations of numerical approximations.
