y=cosѲ → 2 cosѲ 2 in front means there is a vertical expansion of 2
y= cosѲ → cosѲ +1 +1 means the graph will move up 1 on the center line (vertical displacement)
y=1/4sinѲ ¼ treat as 1’s on your y-axis, instead of 1 and -1 it will be ¼ and -1/4
y= sin( Ѳ + π/2) ← π/2 this is called a phase shift, it will move to the left π/2
y= cos (Ѳ - π/3)
→ π/3 1/4P = π/2 Phase Shift: = π/3 = 2 π/6 Scale: (common denominator) π/6
