Trigonometry
You will be able to:
- calculate the trigonometric ratios for a given right-angle triangle ()
- solve for an angle using inverse trigonometric functions
- solve oblique triangles using Sine Law and Cosine Law
- define a radian; be able to convert from radians to degrees and degrees to radians
- know the trigonometric ratios for a 30-60-90 degree triangle and a 45-45-90 degree triangle
- be able to determine other angles with the same \cos-value, \sin-value, and \tan-value as a given angle (use the CAST rule or the unit circle)
