![### Educational Content on Differential Equations
**1. Verification Problem**
Verify that \( y(x) = c_1 \sin x + c_2 \cos x - (\cos x) \ln(\sec x + \tan x) \) is a solution to the differential equation:
\[
y'' + y = \tan x
\]
**2. Function Derivation Problem**
Find a function \( f \) such that:
\[
f'(x) = x f(x) - x \quad \text{and} \quad f(0) = 2
\]
**3. Differential Equation Problem**
Solve the differential equation:
\[
\frac{dP}{dt} = kP \left( 1 - \frac{P}{M} \right) \left( 1 - \frac{m}{P} \right)
\]
where \( k \), \( M \), and \( m \) are constants.
**Explanation:**
- The first problem involves verifying a given function as a solution to a given second-order differential equation.
- The second problem requires finding a function given its derivative and an initial condition.
- The third problem asks for solving a differential equation that incorporates logistic growth and an additional factor, with \( k \), \( M \), and \( m \) representing constant parameters in the problem.
Note that solving these problems involves applying methods from calculus, such as solving ordinary differential equations, applying initial conditions, and using integration techniques.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd28c33a3-d354-4b24-ba8d-accf002943b8%2Febbad0d6-69c4-4088-b863-df65be2812ce%2Fh7ibv59_processed.jpeg&w=3840&q=75)
