9758 MATHEMATICS GCE ADVANCED LEVEL H2 SYLLABUSPREAMBLEMathematics is a basic and important discipline that contributes to the developments and understandings ofsciences and other disciplines. It is used by scientists, engineers, business analysts and psychologists, etc. tomodel, understand and solve problems in their respective fields. A good foundation in mathematics and theability to reason mathematically are therefore essential for students to be successful in their pursuit of variousdisciplines.H2 Mathematics is designed to prepare students for a range of university courses, including mathematics,sciences, engineering and related courses, where a good foundation in mathematics is required. It developsmathematical thinking and reasoning skills that are essential for further learning of mathematics. Throughapplications of mathematics, students also develop an appreciation of mathematics and its connections to otherdisciplines and to the real world.SYLLABUS AIMSThe aims of H2 Mathematics are to enable students to:(a) acquire mathematical concepts and skills to prepare for their tertiary studies in mathematics, sciences,engineering and other related disciplines(b) develop thinking, reasoning, communication and modelling skills through a mathematical approach toproblem-solving(c) connect ideas within mathematics and apply mathematics in the contexts of sciences, engineering andother related disciplines(d) experience and appreciate the nature and beauty of mathematics and its value in life and other disciplines.ASSESSMENT OBJECTIVES (AO)There are three levels of assessment objectives for the examination.The assessment will test candidates' abilities to:AO1Understand and apply mathematical concepts and skills in a variety of problems, including those thatmay be set in unfamiliar contexts, or require integration of concepts and skills from more than onetopic.AO2Formulate real-world problems mathematically, solve the mathematical problems, interpret andevaluate the mathematical solutions in the context of the problems.AO3Reason and communicate mathematically through making deductions and writing mathematicalexplanations, arguments and proofs.3

9758 MATHEMATICS GCE ADVANCED LEVEL H2 SYLLABUSUSE OF A GRAPHING CALCULATOR (GC)The use of an approved GC without computer algebra system will be expected. The examination papers will beset with the assumption that candidates will have access to GC. As a general rule, unsupported answersobtained from GC are allowed unless the question states otherwise. Where unsupported answers from GC arenot allowed, candidates are required to present the mathematical steps using mathematical notations and notcalculator commands. For questions where graphs are used to find a solution, candidates should sketch thesegraphs as part of their answers. Incorrect answers without working will receive no marks. However, if there iswritten evidence of using GC correctly, method marks may be awarded.Students should be aware that there are limitations inherent in GC. For example, answers obtained by tracingalong a graph to find roots of an equation may not produce the required accuracy.LIST OF FORMULAE AND STATISTICAL TABLESCandidates will be provided in the examination with a list of formulae and statistical tables.INTEGRATION AND APPLICATIONNotwithstanding the presentation of the topics in the syllabus document, it is envisaged that some examinationquestions may integrate ideas from more than one topic, and that topics may be tested in the contexts ofproblem solving and application of mathematics.Possible list of H2 Mathematics applications and contexts:Applications and contextsSome possible topics involvedKinematics and dynamics (e.g. free fall, projectilemotion, collisions)Functions; Calculus; VectorsOptimisation problems (e.g. maximising strength,minimising surface area)Inequalities; System of linear equations; CalculusElectrical circuitsComplex numbers; CalculusPopulation growth, radioactive decay, heating andcooling problemsDifferential equationsFinancial maths (e.g. banking, insurance)Sequences and series; Probability; SamplingdistributionsStandardised testingNormal distribution; ProbabilityMarket research (e.g. consumer preferences, productclaims)Sampling distributions; Hypothesis testing;Correlation and regressionClinical research (e.g. correlation studies)Sampling distributions; Hypothesis testing;Correlation and regressionThe list illustrates some types of contexts in which the mathematics learnt in the syllabus may be applied, and isby no means exhaustive. While problems may be set based on these contexts, no assumptions will be madeabout the knowledge of these contexts. All information will be self-contained within the problem.4
