Cambridge IGCSE Additional Mathematics (0606)

IGCSE Additional Maths, one step further.

Q: Do I need to take IGCSE Maths as well?

The syllabus assumes you know IGCSE Mathematics content, including indices and surds. Most students take both, often in the same year. Your tutor can fill gaps from 0580 as they come up.

Q: Is Additional Maths good preparation for A Level?

It covers topics, such as calculus, logarithms and the coordinate geometry of the circle, that come up again in AS & A Level Mathematics. Tell your tutor if you’re planning to go on, and it can point out the links.

Q: Can it help with proving trigonometric identities?

Yes. Your tutor shows one line at a time, which identity each step uses, and lets you try the next line first.

Q: Is it free to use for Cambridge IGCSE Additional Mathematics?

Yes. The free plan includes 5 tutor messages and 15 minutes of calls a day. Pro and Max give you more when exams get close.

Additional Maths builds on IGCSE Maths with functions, logarithms and calculus. Your tutor works through each method with you and checks every line, because both papers want the working shown.

Find the values of k for which the equation x² + kx + 9 = 0 has two distinct real roots.[3 marks]

This is worth 3 marks. They go for:

Use the discriminant: k² − 4 × 1 × 9 > 0 (1 mark)
k² > 36, so the critical values are k = −6 and k = 6 (1 mark)
k < −6 or k > 6 (1 mark)

Examiner tip: Two distinct roots means b² − 4ac > 0, not ≥ 0. Writing −6 < k < 6 is the most common slip.

Common Cambridge IGCSE Additional Maths mistakes

Treating Paper 1 like Paper 2.
Paper 1 has no calculator, so learn exact values (sin 30° = ½, ln 1 = 0) and leave answers as surds or in terms of π where the question allows.
Working in degrees during calculus or circular measure.
Arc length rθ, sector area ½r²θ and the derivatives of sin and cos all need θ in radians. Check your calculator mode on Paper 2.
Dropping the constant of integration.
Add + c to every indefinite integral. If the question gives a point on the curve, use it to find c.
