Question 564783: Find the amplitude, period and displacement of the function below and use this information to sketch its graph
y=cos(2x+2pi/3)
amp=1
period=pi
displacement=-2pi/6 Ithink
But I cant figure out how to do all plotting points to graph please help me!!

Find the amplitude, period and displacement of the function below and use this information to sketch its graph
y=cos(2x+2pi/3)
amp=1
period=pi
displacement=-2pi/6 = -(1/3)pi

You have all the information you need.

Start the peak of the cosine curve x = -(1/3)pi.
The y-intercept is at (0,cos((2/3)pi) = (0, -1/2)
continue the curve to the right and to the left
remembering that the period is pi.
