Detailed Solutions for the June 2013 Maths 2 Paper

Below is a comprehensive solution guide for each question from the June 2013 Maths 2 paper. These solutions are designed to help students grasp the core concepts and methodologies required to solve similar problems.

Question 1: Differential Calculus

Question: Find the maximum value of the function \(f(x) = x^3 - 6x^2 + 9x + 2\).

Solution:

1. Find the first derivative:

\[

f'(x) = 3x^2 - 12x + 9

\]

2. Set the derivative to zero to find critical points:

\[

3x^2 - 12x + 9 = 0

\]

\[

x^2 - 4x + 3 = 0

\]

\[

(x - 1)(x - 3) = 0

\]

So, critical points are at \(x = 1\) and \(x = 3\).

3. Evaluate \(f(x)\) at critical points:

• At \(x=1\):

\[

f(1) = 1 - 6 + 9 + 2 = 6

\]

• At \(x=3\):

\[

f(3) = 27 - 54 + 27 + 2 = 2

\]

4. Determine maximum:

Since \(f(1) = 6\) and \(f(3) = 2\), the maximum value of \(f(x)\) on the real line is 6 at \(x=1\).

Question 2: Integration

Question: Evaluate \(\int_{0}^{2} (x^2 + 3x) dx\).

Solution:

1. Integrate term by term:

\[

\int (x^2 + 3x) dx = \frac{x^3}{3} + \frac{3x^2}{2} + C

\]

2. Apply limits from 0 to 2:

\[

\left[\frac{x^3}{3} + \frac{3x^2}{2}\right]_0^{2}

\]

• At \(x=2\):

\[

\frac{8}{3} + \frac{3 \times 4}{2} = \frac{8}{3} + 6 = \frac{8}{3} + \frac{18}{3} = \frac{26}{3}

\]

• At \(x=0\):

\[

0 + 0 = 0

\]

3. Result:

\[

\boxed{\frac{26}{3}}

\]

Question 3: Differential Equation

Question: Solve the differential equation \(\frac{dy}{dx} = y\).

Solution:

1. Recognize the form:

\[

\frac{dy}{dx} = y

\]

This is a first-order linear differential equation.

2. Separate variables:

\[

\frac{dy}{y} = dx

\]

3. Integrate both sides:

\[

\int \frac{1}{y} dy = \int dx

\]

\[

\ln |y| = x + C

\]

4. Solve for \(y\):

\[

y = \pm e^{x + C} = Ae^{x}

\]

where \(A = \pm e^{C}\) is an arbitrary constant.

Final solution:

\[

\boxed{y = Ae^{x}}

\]

Question 4: Vector Calculus

Question: Find \(\nabla \cdot \vec{F}\) for \(\vec{F} = x^2 \hat{i} + y^2 \hat{j} + z^2 \hat{k}\).

Solution:

1. Compute divergence:

\[

\nabla \cdot \vec{F} = \frac{\partial}{\partial x} (x^2) + \frac{\partial}{\partial y} (y^2) + \frac{\partial}{\partial z} (z^2)

\]

2. Calculate derivatives:

\[

2x + 2y + 2z

\]

Answer:

\[

\boxed{2(x + y + z)}

\]
