4 The Cosine Function In this lesson we investigate the effects of changing the amplitude and period of the standard cosine function We also look at the effects of p and q and explain to learners how like in other functions these variables shift the graph up, down, left and right 5 Sketching and Determine the Equation of the Cosine Function
