Homework Help: Trig help?

Posted by Kay on Tuesday, February 3, 2009 at 5:02pm.

The question is:
State the vertical shift and the equation of the midline for y = 4cosθ-1?

I have NO idea what to do here. Can someone possibly show me step by step? I am more of a visual learner, if I see something done I can usually understand it.
