Edexcel A Level Maths: Pure:复习笔记2.13.1 Further Modelling with Functions
Further Modelling with Functions
Assumptions, criticisms and refinements in modelling
- Modelling is a large part of A level mathematics
- Assumptions and refinements to models often need to be considered
- Real-life general knowledge and common sense can really help in mathematical modelling
How do I solve modelling problems?
- There will be no one-size-fits-all step-by-step guide to solving modelling questions
- A combination of skills and problem-solving skills will be needed
Exam Tip
- Reciprocal graphs generally have two parts/curves
- Only one – usually the positive – may be relevant to the model
- Think about why x/t/θ can only take positive values?
