Math Problem Statement
Solution
The question is asking which of the given differential equations is of the variable separable type. In variable separable equations, the differential equation can be rewritten such that all terms involving are on one side and all terms involving are on the other side. Let's examine each equation to check for separability.
Option A:
This equation has mixed terms involving both and on both sides of the equation, and it cannot be easily separated into functions of and alone. Not separable.
Option B:
This equation can be rewritten as: This is not separable because and are multiplied together, and it cannot be easily rearranged into a separable form. Not separable.
Option C:
This equation has complex terms involving both and inside exponentials and products, making it hard to separate into terms solely involving and . Not separable.
Option D:
This equation can be separated because the terms involving and can be divided and moved to opposite sides: While it appears complicated, it is possible to manipulate this equation into a separable form. Separable.
Answer:
Option D is the variable separable differential equation.
