1: I admit I fell off the bus a few times this semester.
2: so many | Trigonometric Function Values of an Acute Angle | is the acute angle of a right triangle. Remember: Some Old Hippie Caught Another Hippie Tripping On Asphalt
3: Trigonometric Functions of any Angle
4: Reference Angles | The reference angle for an angle is the acute angle formed by the terminal side of the angle and the x-axis. | The reference angles can be 30,45, and 60 degrees.
5: Half-Angle Identities | Remember: Its sin,cos, and tan sin and cos have one, while tan has two.
6: Product-to-Sum Identities | Remember: (sin)(cos) (cos)(sin) (cos)(cos) (sin)(sin) Product-to-Sum is multiplication. on the right side for the first two its sin+sin & sin-sin, for the last two its cos+cos & cos-cos.
7: Sum-to-Product Identities | Remember: sin+sin sin-sin cos+cos cos-cos Sum-to-Product is addition and subtraction.
8: Unit Circle | Remember: 0+30=30 30+15=45 45+15=60 60+30=90 You add 30 then 15 then 15 then 30 and it continues like that around the circle.
9: The Law of Cosines | Remember: When you have a^2= you find cos A, when you have b^2= you find cos B, and when you have c^2= you find cos C.
