Differential Equations Concepts Review

The video tutorial explains how to solve a separable differential equation. It starts by introducing the problem and initial conditions, then demonstrates the separation of variables. The process of integrating both sides of the equation is shown, followed by finding the constant using initial conditions. Finally, the particular solution is derived, and the solution is concluded.
