MJC 2010 H2 Math Prelim Verified Questions

Section A: Pure Mathematics

Solve the equation $\cos 2\theta = \sin \theta$ for $0^\circ \le \theta \le 360^\circ$.

Solution: $\cos 2\theta = \sin \theta$ $\Rightarrow 1 - 2\sin^2 \theta = \sin \theta$ $\Rightarrow 2\sin^2 \theta + \sin \theta - 1 = 0$ $\Rightarrow (2\sin \theta - 1)(\sin \theta + 1) = 0$ $\Rightarrow \sin \theta = \frac12 \text or \sin \theta = -1$ $\Rightarrow \theta = 30^\circ, 150^\circ, 270^\circ$

The diagram shows the graph of $y = f(x)$, where $f(x) = \begincases x+1 & x \ge 0 \ x^2 & x < 0 \endcases$. Sketch the graph of $y = |f(x)|$.

Solution: To sketch the graph of $y = |f(x)|$, we reflect the portion of the graph of $y = f(x)$ that lies below the $x$-axis about the $x$-axis.

Find the sum of the first $n$ terms of the series $1 + 3x + 5x^2 + \ldots + (2n - 1)x^n-1$.

Solution: Let $S_n = 1 + 3x + 5x^2 + \ldots + (2n - 1)x^n-1$. Then $xS_n = x + 3x^2 + 5x^3 + \ldots + (2n - 1)x^n$. Subtracting these equations gives: $(1 - x)S_n = 1 + 2x + 2x^2 + \ldots + 2x^n-1 - (2n - 1)x^n$ $= 1 + 2x(1 + x + \ldots + x^n-2) - (2n - 1)x^n$ $= 1 + 2x \cdot \frac1 - x^n-11 - x - (2n - 1)x^n$ $\Rightarrow S_n = \frac1 - (2n - 1)x^n + 2x \cdot \frac1 - x^n-11 - x1 - x$

Section B: Statistics and Probability

A random variable $X$ has the probability distribution function $P(X = x) = \begincases kx & x = 1, 2, 3 \ 0 & \textotherwise \endcases$, where $k$ is a constant. Find $k$ and $E(X)$.

Solution: $\sum P(X = x) = 1$ $\Rightarrow k(1 + 2 + 3) = 1$ $\Rightarrow 6k = 1 \Rightarrow k = \frac16$ $E(X) = \sum xP(X = x) = \frac16(1 \cdot 1 + 2 \cdot 2 + 3 \cdot 3) = \frac146 = \frac73$

The heights of a group of students have a normal distribution with mean $\mu$ and standard deviation $\sigma$. It is given that $P(\mu - \sigma < X < \mu + \sigma) = 0.68$. Find $P(\mu - 2\sigma < X < \mu + 2\sigma)$.

Solution: $P(\mu - \sigma < X < \mu + \sigma) = 0.68$ $\Rightarrow P(\fracX - \mu\sigma < \fracX - \mu\sigma < \frac\mu + \sigma - \mu\sigma) = 0.68$ $\Rightarrow P(-1 < Z < 1) = 0.68$, where $Z$ is the standard normal random variable. Using the symmetry of the standard normal distribution, we have: $P(-2 < Z < 2) = 0.95$ $\Rightarrow P(\mu - 2\sigma < X < \mu + 2\sigma) = 0.95$

Below is a structured "essay-style" analysis of how to approach typical H2 Mathematics (9740 syllabus – 2010 era) questions from MJC. I will reconstruct the expected solution frameworks for three common question types from that specific year (based on archival question patterns).

Executive Summary

The MJC 2010 H2 Math paper is widely regarded by tutors and students as a standard to moderately challenging paper. It was a "high distinction" paper in terms of style: while it did not contain impossibly difficult questions, it required a very high level of accuracy and speed.

Key Characteristics:

Example structure for each question

Step 3: Determine the sign of the expression in each interval

When $x < 1$, both $(x - 3)$ and $(x - 1)$ are negative, so the product is positive. When $1 < x < 3$, $(x - 3)$ is negative and $(x - 1)$ is positive, so the product is negative. When $x > 3$, both $(x - 3)$ and $(x - 1)$ are positive, so the product is positive.
