The amplitude is the highest the function ever gets. That happens when the
cosine is ' 1 '. At that point, the value of the function is<em> 5/2 </em>.
The period is the first time after zero that the angle in the cosine is 2π .
x/2 = 2π
Multiply each side by 2 : x = 4π
The period is <em>4π .</em>

Here is the full question :
Arthur is organising his collection of DVDs He has 112 altogether. The ratio of comedy films to action to horror is 4 : 7 : 3
How many of each type of DVD does he have?
the number of each dvd arthur has = ratio / sum of ratios) x total number of DVDs
Sum of ratios = 4 + 7 + 3 = 14
Comedy films = (4/14) x 112 = 32
Action = (7/14) x 112 = 56
Horror = (3/14) x 112 = 24
