1. Use special triangles. (SPIN....SKETCH...SOLVE) 1 A 1 2 3 + Sin- 7 6 5 Cos 3 3 Sin 4 1 2 5 Cos 6 2. State the amplitude, period, phase shift and vertical shift of each of the following: a) y = 3 sin =3sin(x-1)-2 [2] amplitude: period: phase shift: vertical shift: b) y = 2sin(3x-180)+2 [3] amplitude: period: phase shift: vertical shift: 3. Differentiate: y = 3xSinX y = 5Cos(3x) y = Sin (3x+)Cos (2x)
