Question

Determine the amplitude or period as requested. Amplitude of y = 1/2 * cos 5x

Answer 1

The amplitude is
`(1)/(2) = 0.5`

Explanation:

Trigonometric function:

A trigonometric function has the following format:

`Asin(bx)` or
`A\cos[bx}`

In which the amplitude is A and the period is
`(2\pi)/(b)`

Amplitude of y = 1/2 * cos 5x

The multiplier is 1/2, so this is the amplitude.
