Exploring Differential Equations and Slope Fields

The video tutorial covers a differential equation problem from the 2016 calculus exam. It begins with creating a slope field, followed by using a tangent line for approximation. The tutorial then finds the particular solution to the equation and concludes with a discussion on the domain. The instructor provides step-by-step guidance, emphasizing the importance of separating variables and integrating to solve differential equations.
