Sample SACE Stage 2 Mathematical Methods Practice Questions

Try these sample questions to review concepts for the SACE Stage 2 Mathematical Methods exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the derivative of f(x) = 5e^{3x} with respect to x?
A.5e^{3x}
B.15e^{3x}
C.15e^{2x}
D.5e^{3x} + 3
Explanation: Applying the exponential chain rule d/dx(e^{kx}) = k e^{kx}, the derivative of 5e^{3x} is 5 * 3e^{3x} = 15e^{3x}.
2Find the derivative f'(x) of the function f(x) = ln(4x^2 + 1).
A.8x / (4x^2 + 1)
B.1 / (4x^2 + 1)
C.8x (4x^2 + 1)
D.4x / (4x^2 + 1)
Explanation: Using the chain rule for natural logarithms d/dx[ln(u)] = u'/u with u = 4x^2 + 1, we get u' = 8x, yielding f'(x) = 8x / (4x^2 + 1).
3What is the derivative of f(x) = sin(3x)?
A.cos(3x)
B.3 cos(3x)
C.-3 cos(3x)
D.3 sin(3x)
Explanation: Applying the chain rule for trigonometric functions d/dx[sin(kx)] = k cos(kx), the derivative of sin(3x) is 3 cos(3x).
4A discrete random variable X has probability distribution P(X=1)=0.1, P(X=2)=0.3, P(X=3)=0.4, and P(X=4)=0.2. What is the expected value E(X)?
A.2.5
B.2.7
C.3.0
D.2.8
Explanation: The expected value is E(X) = sum(x * P(X=x)) = (1 * 0.1) + (2 * 0.3) + (3 * 0.4) + (4 * 0.2) = 0.1 + 0.6 + 1.2 + 0.8 = 2.7.
5Find the indefinite integral integral(6x^2 - 4x + 3) dx.
A.2x^3 - 2x^2 + 3x + C
B.18x^3 - 8x^2 + 3x + C
C.2x^3 - 4x^2 + 3x + C
D.6x^3 - 2x^2 + 3x + C
Explanation: Integrating term-by-term using integral(x^n dx) = x^{n+1}/(n+1) gives 6(x^3/3) - 4(x^2/2) + 3x + C = 2x^3 - 2x^2 + 3x + C.
6Evaluate the definite integral integral_0^2 (3e^{2x}) dx.
A.(3/2)(e^4 - 1)
B.3(e^4 - 1)
C.(3/2)e^4
D.3e^4 - 3
Explanation: An antiderivative of 3e^{2x} is (3/2)e^{2x}. Evaluating from 0 to 2 yields (3/2)e^4 - (3/2)e^0 = (3/2)(e^4 - 1).
7A continuous random variable X has probability density function f(x) = kx for 0 <= x <= 4, and f(x) = 0 elsewhere. Find the value of k.
A.1/16
B.0.125
C.0.25
D.0.5
Explanation: For f(x) to be a valid PDF, integral_0^4 (kx) dx = 1. Evaluating gives k [x^2/2]_0^4 = k(8) = 1, so k = 1/8 = 0.125.
8In a sample of n = 150 individuals, X = 45 possess a specific attribute. Calculate the sample proportion p-hat.
A.0.25
B.0.30
C.0.33
D.0.45
Explanation: The sample proportion is calculated as p-hat = X / n = 45 / 150 = 0.30.
9Solve the equation e^{2x} = 7 for x.
A.x = (1/2) ln 7
B.x = ln 3.5
C.x = 2 ln 7
D.x = ln 14
Explanation: Taking the natural logarithm of both sides gives 2x = ln 7, so x = (1/2) ln 7.
10Find the gradient of the tangent line to the curve y = 3 cos(2x) at x = pi/6.
A.-3 sqrt(3)
B.3 sqrt(3)
C.-3
D.3/2
Explanation: The derivative is dy/dx = -6 sin(2x). At x = pi/6, 2x = pi/3, so dy/dx = -6 sin(pi/3) = -6 (sqrt(3)/2) = -3 sqrt(3).

SACE Stage 2 Mathematical Methods: Suggested Study Strategy

1Master core calculus rules (product, quotient, chain rule) and always simplify expressions carefully before setting derivatives to zero in optimization problems.
2Practice exact anti-differentiation techniques and check limits of integration when finding areas under curves or net versus total distance in kinematics.
3Understand the parameters of discrete and continuous random variables: calculate E(X) and Var(X) accurately, and memorize binomial formulas E(X) = np and Var(X) = np(1-p).
4Use z-scores Z = (X - mu)/sigma to standardize normal random variables and practice solving inverse normal problems for unknown population parameters or cutoff values.
5Memorize the 95% confidence interval formula for population proportions p-hat ± 1.96 * sqrt(p-hat*(1-p-hat)/n) and understand how sample size affects margin of error.
