What MATH1061 covers
Seven examinable topics across two parallel streams → one exam-ready map. Each links to its free chapter guide.
Limits and Continuity
Function families · limit laws · squeeze · continuity · IVTA limit describes what a function approaches as its input approaches a point — near the point, never necessarily at it.
- 1.1 Three tests you reuse all year (the substitution / factor / squeeze trichotomy)
- 1.2 The function families you must know cold
- 1.3 The limit laws — building big limits from small ones
- One-sided limits and when the two-sided limit exists
- 1.4 Reading the picture — limits from a graph
- The squeeze (sandwich) theorem
Differentiation
Difference quotient · product/quotient/chain · implicit · L'Hôpital · optimisationThe derivative is the slope of the tangent line — defined as the limit of the difference quotient, f′(a) = limh→0 [f(a+h) − f(a)]/h — and it runs the whole computational core of the calculus stream.
- 3.1 The derivative as a limit — the difference quotient
- 3.2 The differentiation rules (power, product, quotient, chain)
- 3.3 The standard-derivative table — memorise cold
- 3.4 Implicit and logarithmic differentiation
- 3.5 Application I — L'Hôpital's rule for 0/0 and ∞/∞
- 3.6 Application II — optimisation (f′ = 0, then classify)
Integration
Riemann sum · FTC · substitution · by parts · areas & volumesIntegration is differentiation run backwards — and, separately, the measure of accumulation and area.
- 4.1 Antiderivatives — the standard table
- 4.2 The definite integral as area — Riemann sums
- 4.3 The Fundamental Theorem of Calculus (both parts)
- 4.4 Technique I — substitution (reverse chain rule)
- 4.5 Technique II — integration by parts (reverse product rule)
- 4.6 Technique III — partial fractions
Series
Sequences · geometric series · Taylor & Maclaurin · Lagrange remainderThis stream-closing calculus chapter is Taylor-centric: it is not a full ratio/root/alternating-test battery, but the ideas that MATH1061 actually examines — sequence convergence, the geometric series (the one infinite sum with a clean closed form, a/(1 − r) for |r| < 1), and above all Taylor and Maclaurin polynomials.
- Sequences and their limits — where the terms settle
- The geometric series — converges iff |r| < 1, to a/(1 − r)
- Taylor & Maclaurin polynomials — match value and first n derivatives at a
- The standard Maclaurin series — five expansions to know cold
- The Lagrange remainder — bounding the approximation error
- The exp–log pair and convergence by the integral (p-test)
Complex Numbers
Cartesian & polar · Argand · Euler · de Moivre · roots of unityComplex numbers open the Linear Algebra stream (Weeks 1–2) and are pure procedure once you accept one new symbol: set i² = −1 and treat z = a + bi like an ordinary binomial — add, multiply, conjugate, and divide by realising the denominator.
- Complex arithmetic — i² = −1, add/multiply/conjugate/divide
- The Argand diagram — modulus and argument
- Polar & exponential form — Euler's formula re^{iθ}
- de Moivre's theorem — powers as a single angle multiplication
- Roots of unity and n-th roots — equally spaced on a circle
- The unit circle & trig connection
Vectors
Dot product · angle · projection · cross product · lines & planesA vector is an ordered list of numbers — geometrically an arrow you can add, scale and measure — and it is the language of every later linear-algebra topic.
- B4 Vector arithmetic, length and the parallelogram law
- B5 The dot product, angle and orthogonality
- B5 Projection of one vector onto another
- B6 The cross product in ℝ³ — the right-hand rule, parallelogram area
- B7 Lines in ℝ³ — vector / parametric form
- B7 Planes in ℝ³ — normal form, distances and angles
Matrices
Gaussian elimination · RREF · inverse · determinant · eigenvaluesA matrix is a rectangular grid of numbers that adds, multiplies and — most importantly — transforms space; it is the engine behind every system, inverse and eigen-problem in the course.
- B9 Matrix operations — addition, scalar multiple, the dimension rule for products
- B8 Gaussian elimination — the three row operations → REF / RREF
- B8 Solving Ax = b by row-reduction and back-substitution
- B10 Transpose and the inverse (2×2 and row-reduction methods)
- B11 The determinant by cofactor expansion
- B12–B13 Eigenvalues, eigenvectors and diagonalisation A = PDP⁻¹
The final exam is 60% of your grade, the single biggest lever, and it samples both streams across the whole year; the in-person Quiz A (15%, Week 8) is no-calculator.
Because almost every mark is procedural — take a function, limit, matrix or complex number and produce the exact value — this guide teaches each technique to exam standard: the method in steps, the worked example with real arithmetic, and the trap that loses the mark.

A limit by factor-and-cancel — the signature 0/0 calculation, mark by mark
- +1Test the substitution: putting x = 3 gives (9 − 9)/(3 − 3) = 0/0 — an indeterminate form, so the limit is not yet decided and direct substitution is illegal here.
- +1Factor the numerator: x² − 9 = (x − 3)(x + 3), a difference of two squares.
- +1Cancel the common factor: for x ≠ 3, (x − 3)(x + 3) / (x − 3) = x + 3. The cancellation is valid because a limit only cares about x near 3, never x = 3 itself.
- +1Substitute now: the reduced function x + 3 is continuous, so limx→3 (x + 3) = 3 + 3 = 6.
- +1Justify: you could not substitute at the start because the original quotient is undefined at x = 3 (0/0); only after removing the removable factor is substitution legitimate.
Key terms
- Limit
- The value a function f(x) approaches as x approaches a point a, written limx→a f(x). It describes behaviour near a, not the value at a, which is why a limit can exist where the function is undefined.
- Derivative
- The instantaneous rate of change of a function, defined as the limit of the difference quotient f′(a) = limh→0 [f(a+h) − f(a)] / h. Geometrically it is the slope of the tangent line at the point.
- Fundamental Theorem of Calculus
- The result that links differentiation and integration: the definite integral of a function is found from an antiderivative, ∫ab f = F(b) − F(a), and differentiating an integral recovers the integrand.
- Complex number
- A number of the form z = a + bi where i² = −1. It carries a Cartesian form (a, b) on the Argand plane and a polar form r(cosθ + i sinθ) = reiθ, which makes powers and roots (de Moivre) easy.
- Eigenvalue
- A scalar λ for which a square matrix A satisfies Av = λv for some non-zero vector v (the eigenvector) — a direction the matrix only stretches, never rotates. Found by solving det(A − λI) = 0.
MATH1061 FAQ
Is MATH1061 hard?
It is procedural rather than conceptual, so the difficulty is precision and breadth, not abstraction. The trap is that it is really two courses in one: a Calculus stream and a Linear Algebra stream run in parallel all semester, and you cannot coast on either — Quiz A and the 60% final both cut across the two. Most marks reward applying the right technique cleanly under time.
How is MATH1061 assessed?
The final exam is 60% and samples both streams across the whole year. The rest is an in-person Quiz A (15%, Week 8, no calculators), Assignment 2 (10%), best-8-of-10 weekly online quizzes (8%), Assignment 1 (5%) and tutorial contribution (2%). Confirm this year's exact weights and the final-exam format on your unit's Canvas page.
What is on the MATH1061 final exam?
Both streams. Calculus: function families and limits (laws, squeeze, continuity, IVT), differentiation (rules, chain, implicit, L'Hôpital, optimisation), integration (Riemann sums, FTC, substitution, by parts) and sequences, series & Taylor.
Linear Algebra: complex numbers (polar, de Moivre, roots), vectors (dot/cross product, lines & planes) and matrices (Gaussian elimination, determinants, eigenvalues & diagonalisation).
Can I use a calculator in MATH1061?
Not in the in-person Quiz A (Week 8) — it is explicitly no-calculator, no-notes, so exact-value arithmetic by hand (fractions in lowest terms, surds left as surds) is the whole test. The final exam's conditions are set by the unit; check the official "Information on Final Exam" page, and revise as though it too rewards exact-value work.
Is using AskSia for MATH1061 cheating?
No. AskSia is a study reference written in our own words with our own fresh worked numbers — we host none of your lecturer's files, and Sia teaches you the method to earn the marks; it does not complete or sit your assessments.
Questions students ask in each MATH1061 chapter
- Why can't I just substitute x = a straight away?
- You can — but only when the function is continuous at a. If substitution gives a defined value, that value is the limit. If it gives an indeterminate form like 0/0, substitution is illegal at that point and you must do algebra first (factor and cancel, or rationalise a conjugate). A limit cares about x near a, not at a, which is exactly why the cancelled factor doesn't matter. Chapter 01 · Limits and Continuity
- When do I use the chain rule versus the product rule?
- Product rule is for a product of two functions, (uv)′ = u′v + uv′. Chain rule is for a composition — one function inside another, like (2x − 1)³ or sin(x²). Many problems need both: differentiate the outside with the chain rule, and if the inside is itself a product, use the product rule there. The test is structural: 'multiplied together' → product; 'plugged inside' → chain. Chapter 02 · Differentiation
- How do I pick u for a substitution?
- Choose the inner function whose derivative also appears (up to a constant) elsewhere in the integrand — typically what's inside a power, a root, an exponential or a trig function. After setting u, the whole integrand including dx must rewrite cleanly in u; if leftover x's remain, the choice was wrong. For definite integrals, convert the limits to u rather than back-substituting. Chapter 03 · Integration
- When does a geometric series converge, and what's the sum?
- It converges exactly when the common ratio satisfies |r| < 1; then the infinite sum is a/(1 − r), where a is the first term. If |r| ≥ 1 the terms don't shrink to zero and the series diverges. Spotting the first term a and the ratio r correctly is the whole task — divide consecutive terms to confirm r is constant. Chapter 04 · Series
- How do I divide two complex numbers?
- Multiply the numerator and denominator by the conjugate of the denominator. The denominator becomes the real number a² + b² (because (a + bi)(a − bi) = a² + b²), leaving a real divisor; then split into real and imaginary parts. This 'realising the denominator' is the standard first move for any z₁/z₂. Chapter 05 · Complex Numbers
- What does the dot product tell me?
- Three things at once. Its sign and value, via u·v = ‖u‖‖v‖cos θ, give the angle between the vectors. A dot product of exactly zero means they're orthogonal (perpendicular). And the dot product drives the projection formula. Whenever a question asks about an angle, perpendicularity, or a shadow/component, reach for the dot product first. Chapter 06 · Vectors
- How do I solve a system Ax = b?
- Form the augmented matrix [A | b], then use Gaussian elimination to reduce it to row-echelon (or reduced row-echelon) form. Back-substitute to read off the solution. The shape of the RREF tells you everything: a unique solution, infinitely many (a free variable / row of zeros with consistent right side), or no solution (a row 0 = nonzero). Chapter 07 · Matrices
How to study for the exam
Treat MATH1061 as two disjoint courses sharing one mark and do not leave a stream blank — the Week-8 Quiz A samples the first half of both and the 60% final samples the lot.
Because almost every question is procedural, the highest-return revision is drilling the recurring chains until they are automatic: Calculus — factor/cancel → limit, differentiate → f′ = 0 → classify, sub or parts → integral, standard series → Taylor; Linear Algebra — realise denominator → complex division, dot product → angle, row-reduce → back-substitute, det(A − λI) = 0 → eigenvalues.
Because Quiz A and much of the final are no-calculator, practise exact values by hand on fresh numbers, and show every line — method marks are real even when the final number slips.
