Stage 5 · Trigonometry C (Path) · Apply the sine, cosine and area rules to any triangle and solve related problems · Topic: Pythagoras & trigonometry · Year 9, 10
Use graphing applications to verify the sine rule a/sinA = b/sinB = c/sinC and that the ratios of a side to the sine of the opposite angle is a constant
