Cambridge has updated the syllabus for IGCSE Additional Mathematics in June 2019 to ensure that students can keep up with the current trend in the world of maths. Some topics have been removed and some new topics have been included to equip students with the relevant mathematics skills and knowledge. Below we highlight the 7 major changes in the 2020-2022 additional maths syllabus.

1. Equations, inequalities and graphs

Some contents in the old syllabus have been combined into this new topic called “Equations, inequalities and graphs”. Under this topic, students will be tested on their ability to solve equations and inequalities graphically or algebraically, to form and solve a quadratic equation by using substitution, to sketch the graphs of cubic polynomials and their moduli, and to solve cubic inequalities graphically.

2. Solve Simultaneous Equations by Elimination or Substitution

Previously, students are required to solve simultaneous equations in two unknowns (x, y) with at least one linear equation (y= mx+c). The new syllabus requires the student to solve the simultaneous equations in two unknowns by elimination or substitution, where x and y can have an exponent of one and above. 

3. Find the Equation of Perpendicular Bisector 

Under the straight line graphs topic, besides knowing and using the conditions for two lines to be parallel and perpendicular, students will be tested on finding the equation of perpendicular bisector too.

4. Trigonometry

The old syllabus only required students to draw and use the graphs of y= 𝑎𝑠𝑖(𝑏𝑥) + 𝑐, 𝑦 = 𝑎𝑐𝑜𝑠(𝑏𝑥) + 𝑐, and 𝑦 = 𝑎𝑡𝑎𝑛(𝑏𝑥) + 𝑐, with the conditions that a and b are positive integers and c is an integer. Under the new syllabus, students now have to learn to draw and use the same trigonometry graphs, where b can be a simple fraction (with a denominator of 2, 3, 4, 6, or 8 only) and integer.

5. Arithmetic and Geometric Series

A new topic called “Series” has been introduced and the topic ‘Binomial Expansions’ in the old syllabus has been incorporated into this topic. Students now have to recognise arithmetic and geometric progressions and solve problems involving arithmetic and geometric progressions using the formulae for the nth term and the sum of the first 𝑛 terms. Besides that, students have to learn how to use the condition for the convergence of a geometric progression, and the formula for the sum to infinity of a convergent geometric progression.

6. Differentiation and Integration

In the new syllabus, integration will involve sums of terms in powers of 𝑥 including 1/𝑥 and 1/a𝑥+b and functions of the form (𝑎𝑥 + 𝑏)𝑛 for any rational 𝑛, including 𝑛= -1.

7. Removal of Set Language and Notation, Matrices, and Relative Velocity

The topics of “Set Language and Notation” and “Matrices” are no longer tested in the new syllabus. The subtopic “Relative Velocity” has also been removed from the topic “Vectors in Two Dimensions” to make room for other contents.
