In a function such as sine or cosine, we could also have a translation of the form: \(y = \sin (x - a)^\circ\) where \(a\) is called the phase angle. This is when the graph of the function has ...

What do you think the graph of \(y = \cos 2x^\circ\) would look ... point when \(y = - 1\) The graph looks like: Now try the example questions below.
