Numbers
01
Exponents & surds
Rational exponents, simplifying surds, and solving exponential equations.
Algebra
02
Quadratic equations & nature of roots
Factorise, complete the square, quadratic formula, and Δ = b² − 4ac.
12
Quadratic inequalities
Sketch the parabola, mark critical values, and read the interval where the graph is above or below the x-axis.
Functions
03
Parabola, hyperbola & exponential
Sketch and interpret y = a(x+p)² + q, y = a/(x+p) + q and y = abˣ + q, including intercepts and axes of symmetry.
Function translations
Hyperbola and exponential graphs
The Cartesian plane and common functions
13
Exponential functions & equations
y = abˣ + q. Same bases to solve exponential equations. Horizontal asymptote y = q.
Hyperbola and exponential graphs
Trigonometry
04
Identities, reduction & equations
sin²θ + cos²θ = 1, reduction formulae, and solving trig equations in [0°; 360°].
CAST diagram and the unit circle
11
Sine, cosine & area rules
a/sin A = 2R, cosine rule, and Area = ½ab sin C for any triangle — 2D problems in KZN/Gauteng papers.
Trig graphs and rules for non-right triangles
Geometry
05
Circle geometry
Theorems: angle at centre, angle in a semicircle, cyclic quad, tan-chord, and equal chords.
Circle geometry theorems
Analytical geometry
06
Inclination & circles
Angle of inclination tan θ = m, and equation of a circle (x−a)² + (y−b)² = r².
Finance
07
Nominal vs effective interest
Convert between i_nom and i_eff, and decay (depreciation) of assets.
Probability
08
Dependent events & Venn
Addition rule, independent vs dependent, tree diagrams, and P(A and B) = P(A)×P(B|A).
Probability tree (two stages)
Patterns
09
Quadratic number patterns
First and second differences. Tₙ = an² + bn + c with 2a = second difference.
Statistics
10
Variance, ogives & five-number summary
σ² = Σ(x − x̄)² / n, quartiles from ogives, box-and-whisker, and outliers.
Box-and-whisker plot
Histogram of test scores
Euclidean geometry
14
Proportion & midpoint theorem
A line through the midpoint of one side, parallel to another, bisects the third side. Similar triangles share equal angles.
