Euler's Method and Differential Equations

The video tutorial explains Euler's method for solving differential equations. It sets up a problem where the derivative of y with respect to x is given, and Euler's method is used to approximate the value of y at a specific point. The tutorial walks through the process step-by-step, calculating slopes and updating values, ultimately solving for the initial condition constant k.
