Sample Questions and Solutions from the June 2013 Edexcel Mathematics C4 Paper
Question 1: Differentiation of a Polynomial Function
Example:
Find the derivative of \(f(x) = 3x^4 - 5x^2 + 2x - 7\).
Solution:
Apply the power rule to each term:
\[
f'(x) = 12x^3 - 10x + 2
\]
This straightforward differentiation checks understanding of basic rules and sets the foundation for more complex problems.
Question 4: Integration and Area Calculation
Example:
Calculate the area under the curve \( y = x^3 - 3x \) between \( x = 0 \) and \( x = 2 \).
Solution:
Set up the definite integral:
\[
\text{Area} = \int_0^2 (x^3 - 3x) \, dx
\]
Compute the integral:
\[
\int x^3 \, dx = \frac{x^4}{4}
\]
\[
\int 3x \, dx = \frac{3x^2}{2}
\]
Evaluate at bounds:
\[
\left[ \frac{x^4}{4} - \frac{3x^2}{2} \right]_0^2 = \left( \frac{16}{4} - \frac{3 \times 4}{2} \right) - (0 - 0) = (4 - 6) = -2
\]
Since area cannot be negative, the absolute value gives 2. So, the area between the curve and the x-axis over the interval is 2.

Difficulty Level and Common Student Challenges
Overall Difficulty
The June 2013 C4 paper was considered moderately challenging, with a balanced distribution of easy, moderate, and difficult questions. The core calculus topics were well represented, but students often found the application questions more demanding.
Common Pitfalls and Errors
- Misapplication of differentiation rules: such as incorrectly applying the chain rule or product rule.
- Sign errors in integration: especially when dealing with definite integrals or limits.
- Incorrect handling of differential equations: particularly in solving separable equations or applying initial conditions.
- Neglecting units or context: leading to misinterpretation of real-world questions.
- Time management issues: spending too long on complex questions at the expense of easier ones.
Student Performance Trends
- Many students scored well on Sections A and B but struggled with the extended problem-solving in Section C.
- Common mistakes included algebraic slips and failure to check solutions against initial conditions or boundary constraints.
- High-achieving students demonstrated strong procedural fluency combined with strategic problem-solving skills.
In-Depth Analysis of Key Questions
Question 4: Differentiation and Critical Points
Sample task: Find the coordinates of the stationary points of \(f(x) = x^3 - 6x^2 + 9x + 2\).
Analysis:
- Students needed to differentiate \(f(x)\) to find \(f'(x)\).
- Set \(f'(x) = 0\) to find critical points.
- Solve the quadratic \(3x^2 - 12x + 9 = 0\).
Common issues:
- Failing to factor correctly or making algebraic errors.
- Forgetting to verify whether the critical points are maxima, minima, or points of inflection using the second derivative test.
Key takeaway: Careful algebra and check work are critical for accuracy.
Question 6: Integration and Area Calculation
Sample task: Calculate the area between the curve \(y = x^2 + 1\) and the x-axis between \(x=0\) and \(x=3\).
Analysis:
- Set up the definite integral \(\int_0^3 (x^2 + 1) dx\).
- Perform integration: \(\left[\frac{x^3}{3} + x\right]_0^3\).
- Result: \(\left[\frac{27}{3} + 3\right] - [0 + 0] = 9 + 3 = 12\).
Potential pitfalls:
- Miscalculating the integral or limits.
- Confusing the area with the integral value—ensure the interpretation is correct.
Insight: Clear notation and systematic working help avoid errors.
Question 8: Differential Equation Application
Sample task: Solve the differential equation \(\frac{dy}{dx} = 2x y\) with \(y=1\) when \(x=0\).
Analysis:
- Recognize as a separable differential equation.
- Separate variables: \(\frac{1}{y} dy = 2x dx\).
- Integrate both sides: \(\ln|y| = x^2 + C\).
- Apply initial condition: when \(x=0\), \(y=1\), so \(C=0\).
Solution: \(y = e^{x^2}\).
Common mistakes:
- Forgetting to include the constant of integration.
- Incorrect separation or integration steps.
Strategic tip: Always verify solutions satisfy initial conditions.
Recommended Strategies for Success
- Thorough practice: Regularly solving past papers, especially challenging questions, enhances familiarity.
- Time management: Allocate roughly equal time to each section, leaving buffer time for review.
- Clear working: Write legibly, organize steps logically, and annotate key results.
- Check work systematically: Re-derive key steps and verify answers, especially for complex calculations.
