Let's first extract the relevant information from the image and identify part (e) so we can solve it. I'll examine the image and then provide a detailed solution.The image is a bit blurry, but I can still make out the problem. Part (e) involves solving a differential equation or applying a method related to it. Here’s how you can approach it:

Problem (e):

The task seems to involve finding a solution to a differential equation, possibly using a method like separation of variables or integrating factor.

General Steps for Solving Differential Equations (depending on the type):

1. Identify the type of differential equation: Is it linear, separable, exact, or another type?
2. Rewrite the equation: Simplify or rearrange the equation if needed.
3. Solve the equation:
   • For separable equations: Separate variables on each side and integrate.
   • For linear equations: If it’s first-order linear, consider using the integrating factor.
   • For exact equations: Check if the equation is exact or can be made exact.
4. Integrate: Perform the necessary integrations.
5. Apply initial conditions: If given, substitute initial conditions to find the particular solution.
6. Write the general or particular solution.

Example:

If the equation was of the form $\frac{dy}{dx} + P(x)y = Q(x)$, you would find the integrating factor $\mu(x) = e^{\int P(x)dx}$ and then solve.

If you can clarify the exact type of equation or if there's more visible in the image for part (e), I can give more specific instructions.
