Trigonometry
You will be able to:
- calculate the trigonometric ratios for a given right-angle triangle ($\sin, \cos, \tan, \csc, \sec, \cot$)
- 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)
