The domain and the range are 0 ≤ ∅ ≤ 2π and -1 ≤ cos(∅) ≤ 1, respectively.
<h3>The domain and the range</h3>The domain is the set of input values i.e. the ∅ values.
On the table, we can see that the ∅ value is from 0 to 2π.
This means that the domain is 0 ≤ ∅ ≤ 2π
On the other hand, the range is the set of output values i.e. the cos(∅) values.
On the table, we can see that the cos(∅) value is from -1 to 1.
This means that the range is -1 ≤ cos(∅) ≤ 1
Hence, the domain and the range are 0 ≤ ∅ ≤ 2π and -1 ≤ cos(∅) ≤ 1, respectively.
