Separation of Variables
Definition
Separation of variables is a technique used to solve differential equations by isolating the variables on opposite sides of the equation and integrating each side separately.
Analogy
Think of separation of variables like separating ingredients in a recipe. Just as you separate different ingredients to mix them individually, separation of variables allows us to isolate and integrate each variable separately in a differential equation.

Integrating Factors: Integrating factors are used to transform certain types of non-exact differential equations into exact ones, making them easier to solve.
Substitution: Substitution involves replacing one variable with another in order to simplify an equation or integral.
Initial Value Problem (IVP): An initial value problem is a type of differential equation that includes specific values for the dependent variable and its derivative at a given point.
