Horizontal shift - Graph of cosine

Steps to graph the cosine with a horizontal shift.

1 - Find amplitude and period.
2- Start of the period by setting the argument(what's inside the parenthesis) equal to 0.
3 - End of the period by setting the argument(what's inside the parenthesis) equal to the period you just found.
4 - Graph. I recommend four points on the x-axis.

I hate to break this to you, but to calculate the end of the period, you set the argument = 2pi, not pi. The period is indeed pi, but, as drawn, it's only 2pi/3, so, something's amiss. Have another look at it, please.
