Question

What is the range of the graph of `y = cos x`?

Answer 1

`y=|A|cos(x)`, where `|A|` is the amplitude.

`y=1*cos(x)`

`y=cos(x)`

The range for this trig problem is related to the amplitude. The amplitude for this function is 1. This function will oscillate between the `y` values of `-1` and `1.`

The range is `[-1,1].`
