IB Maths AA HL SL 3.3 Applications of trigonometry
Practise modelling bearings, angles of elevation and real distances with trigonometry in diagrams involving heights, paths and locations.
How this is tested
- link a bearing such as 121° to the reverse bearing and show the direction clearly on a diagram
- use tan, sine rule or cosine rule to convert angles of elevation into distances or heights
- interpret the real context first, then solve where and when the event happens
