Non-right-angled trigonometry - faded worked examples
Resource Type: Worked examples, Faded worked examples
Based on the Cognitive Load Theory idea of faded worked examples. These five sheets provide faded worked examples for
- The sine rule - using the sine rule to find a side
- The sine rule - using the sine rule to find an angle
- The cosine rule - using the cosine rule to find a side
- The cosine rule - using the cosine rule to find an angle
- The area formula
