1. Find the amplitude, period, phase shift and vertical translations. 1)`y=sin(x + π/8)` 2)`y=-cos(2x-(3π)/4)` 3)`y=2cos(πx)+1` 4)`y= 9/5 sin(((7π)/12)x + π/10)-3` 5)`y= 2-sin(2x + π/3)` 6)`y = 3 + 3/4cos(π/9 x -π)`

1. Graph two periods for each of the following. 1) `y = sin(x + π/3)` 2) `y=-sin(x)-2` 3) `y=sin(πx+π/2)+3` 4) `y=4sin((2π/5)x +π)+2` 5)` y = cos(x-(3π)/2)` 6)`y=-2sin(4x - (2π)/3)-1`
