Differential Equations and Solutions

The video tutorial explains how to solve a separable differential equation where the derivative of y with respect to x equals 3 times y. The goal is to find a particular solution that satisfies the condition y equals 2 when x equals 1. The instructor guides through recognizing the equation as separable, solving it by integrating both sides, and rewriting the solution in exponential form. Finally, the particular solution is determined by substituting the given condition to solve for the constant.
