Question 860436
Graph each sinusoidal function over two cycles
a) y = 3 cos ( x - π/6)
Sketch a cosine curve
amplitude = 3
phase shift = pi/6 to the right
{{{graph(400,400,-6.5,6.5,-4,4,3cos(x-(pi/6)))}}}
-------------------------------------------
b) y = 2 cos ( x - 5π/3)
Sketch a cosine curve.
Amp = 2
phase shift if (5/3)pi to the right
{{{graph(400,400,-6.5,6.5,-2.5,2.5,2cos(x-(5/3)pi))}}}
-----------------------------------------------------------
c) y = 5 cos ( x + 7π/6)
phase shift to the left
{{{graph(400,400,-6.5,6.5,-10.5,10.5,5cos(x+(7/6)pi))}}}
