All 19 O-Level Additional Maths topics

• Quadratic Functions
  Factorise quadratic expressions (including by grouping, inspection, or using quadratic formula).
• Equations and Inequalities
  Solve quadratic equations by factorisation, completing the square, or using the quadratic formula.
• Surds
  Understand the definition of a surd and its properties.
• Polynomials and Partial Fractions
  Perform polynomial long division by linear or quadratic expressions, understanding that the quotient can be non-linear and the…
• Exponential and Logarithmic Functions
  Apply the laws of indices and logarithms to simplify expressions and solve equations.
• Binomial Theorem
  Expand (a+b)^n for positive integer values of n, where a and b may be constants, expressions in x, or a combination thereof, wr…

• Coordinate Geometry
  Calculate the length of a line segment given the coordinates of its endpoints.
• Circles
  Identify the centre and radius of a circle given its equation in standard form (x − a)² + (y − b)² = r².
• Applications of Straight Line Graphs
  Transform given non-linear equations into the linear form Y = mX + c, identifying the appropriate expressions for Y, X, m, and c.
• Trigonometric Functions
  Understand and use the definitions of trigonometric ratios for angles of any magnitude (including negative angles and angles gr…
• Trigonometric Identities and Equations
  Recall and apply the fundamental trigonometric identities (sin²A + cos²A = 1, sec²A = 1 + tan²A, cosec²A = 1 + cot²A).
• Plane Geometry
  Identify and apply properties of angles and arcs in circles (e.g., angle at centre, angle in semicircle, angles in the same seg…

  Differentiate polynomial functions including ax^n where n is a rational number (including negative and fractional values).
• Tangents, Normals and Rates of Change
  Find the gradient of a tangent to a curve at a given point.
• Maxima and Minima
  Find the first derivative (dy/dx) of a function and set it to zero to find the x-coordinates of stationary points.
• Differentiation of Trigonometric, Exponential and Logarithmic Functions
  Differentiate trigonometric functions (sin x, cos x, tan x) with respect to x.
• Integration
  Integrate standard forms of functions: x^n (for n ≠ -1), (ax+b)^n (for n ≠ -1), 1/(ax+b), e^(ax+b), sin(ax+b), cos(ax+b), and s…
