About This Course
This Additional Mathematics course covers the complete Cambridge O Level (4037) and IGCSE (0606) Additional Mathematics syllabus. Both qualifications are identical in content — this single course fully prepares students for either examination. The course extends well beyond O Level Mathematics into advanced algebra, logarithms and exponentials, advanced trigonometry, and the full calculus (differentiation and integration) with real-world applications. Each lesson follows a structured format: concept explanation, step-by-step worked examples, and graded exam practice questions with full model answers and examiner tips.

📐 Calculus Essentials
- d/dx(eᵃˣ) = aeᵃˣ
- d/dx(ln x) = 1/x
- d/dx(sin ax) = a cos ax
- d/dx(cos ax) = −a sin ax
- d/dx(tan ax) = a sec²ax
- Chain: dy/dx = (dy/du)(du/dx)
- Product: (uv)' = u'v + uv'
- Quotient: (u/v)' = (u'v−uv')/v²
- ∫eᵃˣ = (1/a)eᵃˣ + c
- ∫sin ax = −(1/a)cos ax + c
- ∫1/(ax+b) = (1/a)ln|ax+b| + c
- ∫cos²ax = x/2+sin2ax/4a + c
🔑 Key Formulae
- Discriminant: b²−4ac
- ⁿCᵣ = n!/[r!(n−r)!]
- T_{r+1} = ⁿCᵣ aⁿ⁻ʳ bʳ
- logₐ(xy) = logₐx + logₐy
- logₐ(xⁿ) = n logₐx
- Change base: logₐx=lnx/lna
- sin 2A = 2 sinA cosA
- cos 2A = 2cos²A−1 = 1−2sin²A
- R sin(x+α): R=√(a²+b²)
- tan α = b/a (for a sinx+b cosx)
- General sin: θ=nπ+(−1)ⁿα
- General cos: θ=2nπ±α
⚠ Critical Rules
- fg(x) → apply g FIRST then f
- Domain f⁻¹ = Range of f
- Prove identities: ONE side only
- Check log arguments > 0
- Trig calculus: radians only
- Never divide by trig function
- d²y/dx²=0 → use sign test
- Distance ≠ displacement
- Change limits in substitution
- |area below x-axis| (modulus)
- Improper fraction → divide first
- +c in ALL indefinite integrals
Where Additional Mathematics Leads
Additional Mathematics covers roughly half the A Level Mathematics content — making it the ideal bridge qualification. Students who complete 4037/0606 typically find the transition to A Level Mathematics significantly smoother.
🎯 Top 8 Exam Tips for Cambridge Additional Mathematics (4037 / 0606)
- Show every algebraic step. Method marks are awarded throughout. A correct method with an arithmetic error still earns most marks. Never write just the final answer for multi-mark questions.
- When "hence" appears, use the previous result. Cambridge specifically tests whether you can connect results between parts. Using an independent method when "hence" is specified may lose marks.
- Use radians for all trigonometric calculus. Differentiating or integrating trig functions only works correctly in radians. Check your calculator mode at the start of every calculus question.
- In logarithm equations, always check and reject invalid solutions. State explicitly "reject x=... because log argument < 0." Cambridge mark schemes allocate a mark for this rejection step.
- For identity proofs, work on ONE side only. Never move terms across the ≡ sign. Start with the more complex side. Conclude clearly with "= RHS ✓" or "= LHS ✓."
- For area questions, always sketch the curves first. Mark intersection points, shade the required region, and identify which curve is above the other. Integrating in the wrong order gives a negative area — subtract the lower from the upper.
- For R form questions, adjust the solution range for the shifted angle. If solving R sin(x+α)=k in 0°≤x≤360°, the range for (x+α) is α to 360°+α. Missing solutions outside 0°–360° is a very common error.
- Leave time to check your answers. For stationary points: verify using d²y/dx² or sign test. For trig equations: check all solutions satisfy the original equation. For log equations: verify arguments are positive.
