IB Maths AI SL 1.6 Approximation & error
Students practise calculating absolute and percentage error, determining bounds from rounded measurements, and assessing certainty in derived quantities.
How this is tested
- find smallest possible volume of a sphere using lower bound of diameter in V = ⁴⁄₃πr³
- assess whether speed exceeds limit by computing maximum possible speed using shortest measured time
- calculate percentage error using the true value given or inferred from context
