Revision coverage

Topic checklist

Use this as a revision index. Each card gives the skills to practise, common traps, and a clean generic example style.

Function language

Domain, range, maximal domain, restricted domain, interval notation, endpoint labels, full function notation, and interpreting graphs.

State mappings as $f : D \to R$ , $f (x) = \dots$ .
Check whether endpoints are open or closed.
For inverses, swap domain and range after confirming the function is one-to-one on its stated domain.

sin

Circular functions

Exact values, radians and degrees, signs by quadrant, period, transformations, solving trigonometric equations, and sketching one or more cycles.

Know the unit-circle values for $0, \frac{π}{6}, \frac{π}{4}, \frac{π}{3}, \frac{π}{2}$ .
For $y = a \sin (n (x - h)) + k$ , amplitude is $| a |$ and period is $\frac{2 π}{| n |}$ .
For tangent, period is $\frac{π}{| n |}$ ; vertical asymptotes matter.

Transformations and inverses

Translations, reflections, dilations from axes, transformed rules, inverse rules, inverse domains, and graph-to-rule reasoning.

Horizontal changes happen inside the function and often feel reversed.
When finding an inverse, write $y = f (x)$ , swap $x$ and $y$ , then solve for $y$ .
Transformations can change the domain and range; update both.

Quadratics and optimisation

Vertex form, intercept form, discriminants, parameter conditions, modelling, maximum and minimum values, and domain restrictions.

$Δ = b^{2} - 4 a c$ : two, one, or no real x-intercepts.
Use vertex form when maximum or minimum information is given.
For optimisation, state the variable, rule, domain, and final value in context.

{ }

Piecewise and hybrid functions

Building functions over adjacent domains, graphing endpoints, avoiding overlap, and combining linear, quadratic, circular, or rational sections.

Every piece needs its own rule and interval.
Intervals should cover the intended path without gaps or double-counting endpoints.
Use clear endpoint notation on sketches and in written function definitions.

1/x

Rational and root functions

Asymptotes, intercepts, reciprocal transformations, square-root domains, distances between points, and sketch features.

Denominators cannot be zero.
Square-root inputs must be non-negative unless the domain is already restricted.
Sketches should label intercepts, endpoints, asymptotes, and key transformed points.

Probability

Complements, unions, intersections, tree diagrams, conditional probability, at least statements, and repeated independent trials.

$\Pr (A^{'}) = 1 - \Pr (A)$ .
$\Pr (A | B) = \frac{\Pr (A \cap B)}{\Pr (B)}$ , where $\Pr (B) \neq 0$ .
Translate "at least" by adding cases or using the complement.

Coordinate geometry and algebra

Distance, midpoint, gradients, equations of lines, solving equations exactly, and using algebra to support graph features.

Distance: $d = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2}}$ .
Point-gradient form: $y - y_{1} = m (x - x_{1})$ .
Keep exact values unless a question clearly asks for a decimal.

Trigonometry

Solve $2 \sin (x) - 1 = 0$ for $0 \leq x \leq 2 π$ .
Sketch $y = 2 \cos (3 x) - 1$ for one full cycle.

Core 35 min

Quadratics and inverse functions

Find the rule of a quadratic with turning point $(- 2, 7)$ passing through $(1, - 2)$ .

Study plan

Four-session revision sequence

Functions first

Revise domain, range, notation, inverse functions, rational/root features, and graph labels. Finish with 20 minutes of no-calculator sketching.

Trigonometry

Rebuild the unit circle from memory, solve equations over restricted intervals, then sketch sine, cosine, and tangent transformations.

Quadratics and hybrids

Practise modelling from constraints, discriminant conditions, optimisation, and piecewise rules with non-overlapping domains.

Probability and timed sets

Run tree diagrams and conditional probability drills, then complete timed mixed revision: 60 minutes without CAS and 90 minutes with CAS.

Exam 1 approach

No calculator and no bound reference means fluency matters. Prioritise exact values, clean algebra, known graph shapes, and showing enough working to earn method marks.

Memorise common exact trig values.
Practise expanding, factorising, and solving by hand.
Use a ruler and label graph features clearly.
Check domains before finalising inverse or model answers.

Exam 2 approach

CAS and bound reference are allowed, so prepare efficient workflows. Your reference should support the skills, not bury them in long explanations.

Add CAS steps for solving, graphing, intersections, and maximum/minimum checks.
Include a one-page domain/range and transformations summary.
Have a probability formula block with tree-diagram reminders.
Still write mathematical reasoning in full sentences where required.
