Sample Questions from EAS 203 Engineering Mathematics 2 Solved Paper

Question 1: Solve the Differential Equation \( \frac{dy}{dx} + y \tan x = \sin^2 x \)

Solution:

Step 1: Recognize as a first-order linear ODE.

Step 2: Write in standard form:

\[ \frac{dy}{dx} + P(x) y = Q(x) \]

where \( P(x) = \tan x \), \( Q(x) = \sin^2 x \).

Step 3: Find integrating factor:

\[ \mu(x) = e^{\int P(x) dx} = e^{\int \tan x dx} = e^{-\ln |\cos x|} = \frac{1}{\cos x} \]

Step 4: Multiply entire equation by \( \mu(x) \):

\[ \frac{1}{\cos x} \frac{dy}{dx} + \frac{\tan x}{\cos x} y = \frac{\sin^2 x}{\cos x} \]

which simplifies to:

\[ \frac{d}{dx}\left( \frac{y}{\cos x} \right) = \frac{\sin^2 x}{\cos x} \]

Step 5: Integrate both sides:

\[ \frac{y}{\cos x} = \int \frac{\sin^2 x}{\cos x} dx + C \]

Using \( \sin^2 x = 1 - \cos^2 x \):

\[ \int \frac{1 - \cos^2 x}{\cos x} dx = \int \frac{1}{\cos x} dx - \int \cos x dx \]

\[ = \int \sec x dx - \int \cos x dx \]

\[ = \ln |\sec x + \tan x| - \sin x + C' \]

Thus:

\[ y = \cos x \left( \ln |\sec x + \tan x| - \sin x + C' \right) \]

This is the general solution.
