Understanding Differential Equations through Substitution

The video tutorial explains how to solve an initial value problem using the method of substitution. It covers identifying the substitution for Bernoulli and homogeneous equations, transforming the equation into a linear differential equation, and solving it using an integrating factor. The tutorial also demonstrates integration by parts and finding the particular solution with initial conditions. Finally, it verifies the solution using slope fields.
